Authentication Features You Can Skip in V1 (And Add Later)
Overwhelmed by auth feature checklists? Learn which authentication features you can safely skip in your MVP—and which ones are actually essential. Ship faster without compromising security.

Here's a scenario that plays out constantly: You're building your MVP. You've got your core features scoped out. Then you start looking at authentication providers, and suddenly you're staring at feature lists longer than your actual product roadmap.
Multi-factor authentication. Enterprise SSO. SCIM provisioning. Passkeys. Passwordless magic links. Social login with 12 different providers. Custom domains. Advanced analytics. Webhooks. API rate limiting. Breached password detection. Bot protection. Risk-based authentication.
It's overwhelming. And every vendor's marketing makes it sound like you need all of it on day one.
Here's the truth: you don't.
Most of these features exist for problems you don't have yet. And many of them you may never need. Adding them too early doesn't just waste time—it adds complexity, increases costs, and slows down the launch that actually matters.
This guide will help you separate essential from optional, so you can ship your MVP faster without compromising security or user experience.
The Feature Anxiety Trap
Authentication vendors have every incentive to sell you on features. More features mean higher tiers, bigger contracts, and stickier lock-in. Their pricing pages and feature comparison charts are designed to make you think: "Maybe I need this? What if a customer asks for it?"
This leads to over-engineering. Founders spend weeks integrating and configuring auth features for hypothetical users instead of building the core product for real ones.
The Real Cost of Feature Bloat
The cost isn't just time. It's also:
- Complexity: More features mean more things that can break, more edge cases to test
- Confusion: More options confuse users during signup and reduce conversion
- Money: Advanced features often require higher-tier plans with exponential cost increases
- Focus: Time spent on auth is time not spent on your actual product differentiators
The smarter approach: start with what you actually need today, then add features based on real feedback from real users. Every feature you add should solve a problem you've observed, not one you imagine.
What You Actually Need for V1
Let's start with the essentials—the features you should not skip:
Essential (Don't Skip These)
Email/Password Authentication
This is the baseline. Most users expect it, and it works everywhere. You need:
- Email field with basic validation (format check)
- Password field with minimum length requirement (8+ characters)
- "Forgot password" link that actually works
That's it. Don't overcomplicate with password strength meters, complexity rules requiring special characters, or passwordless options on day one.
Password Reset Flow
Users will forget passwords. You need a way for them to reset without contacting support:
- "Forgot password" flow that sends a reset link to email
- Time-limited reset tokens (1-4 hours is standard)
- Simple "enter new password" form
- Clear confirmation message
This is non-negotiable. Without password reset, every forgotten password becomes a support ticket.
Session Management
Your auth provider should handle this automatically:
- Secure session tokens (JWT or opaque tokens)
- Token validation on protected routes
- Logout functionality that actually clears sessions
- Reasonable session duration (7-30 days)
If your provider doesn't handle sessions for you, find a different provider. This isn't something to build yourself in V1—session security has too many subtle gotchas.
HTTPS
This isn't optional. All authentication must happen over HTTPS. Fortunately, most hosting platforms (Vercel, Netlify, Cloudflare, Render) handle this automatically with free SSL certificates.
Basic Input Validation
Prevent obvious attacks without over-engineering:
- Email format validation
- Password minimum length (8 characters is fine)
- Rate limiting on login attempts (most providers include this)
Your auth provider should handle rate limiting automatically. If they don't, that's a red flag.
Probably Want (But Keep Simple)
One Social Login
If you're going to add social login, start with one provider—Google is the safest bet. It:
- Works on all devices (mobile, tablet, desktop)
- Is trusted by almost everyone (3+ billion users)
- Has high adoption across demographics
- Requires minimal setup
Don't add Google, GitHub, Microsoft, Apple, and Twitter all at once. Pick one, validate that users actually use it (track the signup method), then add more based on demand data.
Email Verification
This confirms users own the email address they registered with. But you have options for how strict to be:
Hard enforcement (blocks login until verified):
- Pro: Ensures clean email list, prevents typos, confirms deliverability
- Con: Adds friction, some users never verify (10-20% drop-off)
Soft enforcement (prompts but doesn't block):
- Pro: Users can start using your product immediately
- Con: Some emails will be invalid, bounces affect deliverability
Recommendation for V1: Soft enforcement unless you absolutely need verified emails (e.g., you're sending transactional emails, password resets, or important notifications). Don't block users from your product over email verification if you can avoid it.
What You Can Safely Skip in V1
Now for the good part—features that sound important but can wait until you have real user demand.
Multi-Factor Authentication (MFA/2FA)
What it is: Requiring a second form of authentication (SMS code, authenticator app, hardware key) beyond password.
Why You Can Skip It
- Low voluntary adoption: Typically only 5-10% of users enable MFA when it's optional
- Adds significant friction: During signup and every login thereafter
- Your V1 data probably isn't that sensitive: Most MVPs don't handle financial, healthcare, or personally identifiable information that requires MFA
- Modern providers have good defaults: Token-based auth with secure sessions is quite secure already
When to Add It
Add MFA when you encounter these specific situations:
- When users explicitly request it (track feature requests)
- When you're handling sensitive data (financial, healthcare, PII)
- When B2B customers require it as part of security reviews
- When compliance requires it (HIPAA, SOC 2, PCI-DSS)
How Hard to Add Later
Difficulty: ⭐ Easy
Most providers let you flip a switch to enable MFA. Users can opt in without any code changes on your end. Implementation time: 30 minutes to 2 hours.
Exception: If you're building in fintech, healthcare, or crypto, you might need MFA from day one for compliance and user trust reasons.
Enterprise SSO (SAML/OIDC)
What it is: Allowing companies to integrate your auth with their identity provider (Okta, Azure AD, Google Workspace, OneLogin) so employees can use their corporate credentials.
Why You Can Skip It
- You don't have enterprise customers yet: SSO is irrelevant until you're selling to companies with 100+ employees
- Complex to test without real customers: You need access to actual IdPs to test properly
- Typically locked behind higher pricing tiers: Many providers charge $100-250/month extra for SSO
- Small businesses don't use SSO: Your early adopters (solopreneurs, startups, SMBs) won't ask for it
When to Add It
Add SSO when these situations arise:
- When your first enterprise prospect requests it during sales (concrete need)
- When you're closing deals with companies that have 100+ employees
- When you're ready to move upmarket and charge enterprise prices
How Hard to Add Later
Difficulty: ⭐ Easy (with the right provider)
Most modern auth platforms let you enable SSO without code changes. Just configure it in the dashboard and provide your customers with metadata URLs. Implementation time: 2-8 hours including testing.
Pro tip: When a sales prospect asks "Do you support SSO?", the answer can be "Yes, we can enable it for your account within 24 hours"—even if you haven't turned it on yet. It's that straightforward to add with modern providers.
SCIM Provisioning
What it is: Automatic user provisioning and deprovisioning based on changes in a company's identity provider. When IT adds a user to Okta, they automatically get an account in your app. When someone leaves the company, their account is auto-disabled.
Why You Can Skip It
- Only needed for IT-managed deployments: Relevant only at large companies (250+ employees)
- No SMB or individual user will ever ask: This is pure enterprise IT territory
- Complex to implement and test properly: Requires careful handling of edge cases
- Requires enterprise SSO to be useful: SCIM without SSO makes no sense
When to Add It
Add SCIM when:
- You have enterprise customers with 250+ seats paying premium prices
- IT departments are the buyer, not end users (top-down sales)
- Customers explicitly request it as a contract requirement
How Hard to Add Later
Difficulty: ⭐⭐ Moderate
SCIM requires more planning than just flipping a switch, but most modern platforms provide SDKs and webhooks that make it manageable. Implementation time: 1-3 days including testing.
Multiple Social Logins
What it is: Sign in with Google, GitHub, Microsoft, Apple, LinkedIn, Twitter, Facebook, TikTok, etc.
Why You Can Skip It (Plural)
- Each provider requires separate setup and testing: API keys, OAuth configurations, callback URLs
- More options paradoxically decrease conversion: The paradox of choice is real—too many buttons confuses users
- Most users have a Google account: Google covers 80%+ of the market
- You can't test what you don't have data for: Without analytics, you're guessing which providers matter
When to Add It
Add additional social logins when:
- Analytics show users trying to use a specific provider (evidence-based decision)
- You're targeting a specific community (developers → GitHub, professionals → LinkedIn)
- One provider at a time, based on demand data (don't add 5 at once)
How Hard to Add Later
Difficulty: ⭐ Very easy
Adding a new OAuth provider is usually just API keys and configuration. No code changes needed beyond the initial social login setup. Implementation time: 30 minutes per provider.
Recommendation: Start with Google only. Add GitHub if you're building for developers. Stop there until you see demand for others in your analytics.
Passwordless / Magic Links
What it is: Authentication without passwords—typically via emailed one-time links or SMS codes that log you in directly.
Why You Can Skip It
- Users still expect the option to set a password: Many people don't trust passwordless yet
- Email-based passwordless adds latency: Waiting for email is slower than typing a password
- SMS-based passwordless costs money: Per-login charges add up quickly ($0.01-0.04 per login)
- It's a nice-to-have, not a must-have: Doesn't solve a critical problem for most apps
When to Add It
Add passwordless when:
- As a progressive enhancement alongside password auth, not a replacement
- When your analytics show users struggling with passwords (support tickets, reset frequency)
- When your user base is less technical (passwordless can reduce friction for non-tech users)
How Hard to Add Later
Difficulty: ⭐ Easy
Most providers support it as an additional option alongside password auth. Implementation time: 2-4 hours.
Note: Passkeys (WebAuthn) are the future of passwordless, but they're not ready for V1. Browser support is still inconsistent, and users don't understand them yet. Great for V2+ once standards mature.
Custom Auth Domains
What it is: Hosting auth on your domain (auth.yoursite.com) instead of the provider's domain (yoursite.auth-provider.com).
Why You Can Skip It
- Your users don't care yet: They're focused on your product, not your auth subdomain
- Zero impact on functionality or security: It's purely cosmetic
- Often requires DNS configuration: CNAME records, SSL certificates, propagation time
- Usually locked behind higher pricing tiers: $50-100/month extra in many cases
When to Add It
Add custom domains when:
- Brand consistency matters more than speed (mature product stage)
- Enterprise customers request it (security policy requirement)
- You're established enough to care about this level of polish (not MVP stage)
How Hard to Add Later
Difficulty: ⭐ Easy
Usually just DNS configuration and a setting in your provider's dashboard. Implementation time: 30 minutes to 2 hours (mostly DNS propagation).
Advanced Auth Analytics
What it is: Detailed analytics on signup conversion, login methods, geographic distribution, device types, funnel analysis, etc.
Why You Can Skip It
- You have bigger product questions: "Do users want my product?" matters more than "Which social login converts better?"
- Your analytics tool can track the basics: Mixpanel, Amplitude, PostHog can track auth events
- Auth analytics matter when optimizing, not when launching: Premature optimization is wasted effort
When to Add It
Add advanced auth analytics when:
- You're optimizing conversion funnels (post-product-market-fit)
- You have enough traffic for data to be meaningful (1,000+ signups/month minimum)
- You've exhausted more impactful optimizations (core product features)
How Hard to Add Later
Difficulty: ⭐ Easy
Most providers include analytics; you just need to start looking at them. For custom tracking, add event logging. Implementation time: 1-2 hours.
Webhooks and Event Streams
What it is: Real-time notifications when auth events happen (user signs up, logs in, resets password, updates profile, etc.).
Why You Can Skip It
- You don't have downstream systems yet: No integrations to trigger, no workflows to automate
- You can query user data directly: Just fetch from the database when needed
- Webhooks add infrastructure complexity: Endpoints to maintain, retry logic, failure handling
When to Add It
Add webhooks when:
- Building integrations with other tools (CRM, email marketing, Slack)
- You need audit logs for compliance (SOC 2, HIPAA)
- You're triggering workflows based on auth events (onboarding emails, team notifications)
How Hard to Add Later
Difficulty: ⭐⭐ Moderate
You'll need to build webhook receivers and handle retries. But your auth provider should make the sending part easy. Implementation time: 4-8 hours.
Bot Protection and Risk-Based Auth
What it is: Advanced security that detects and blocks bots, credential stuffing, brute force attacks, and suspicious logins using ML and behavioral analysis.
Why You Can Skip It
- Modern providers include basic rate limiting: Good enough to prevent simple attacks
- You're not a bot target until you're successful: Bots attack high-value targets
- Advanced protection can block legitimate users: False positives are frustrating (CAPTCHA hell)
When to Add It
Add advanced bot protection when:
- You're seeing actual bot traffic in your logs (evidence of attacks)
- You're a high-value target (fintech, crypto, e-commerce with fraud risk)
- After you've grown enough to be worth attacking (100K+ users typically)
How Hard to Add Later
Difficulty: ⭐-⭐⭐ Easy to moderate
Most providers offer this as a feature you can enable. Some require integration work. Implementation time: 2-8 hours depending on sophistication.
The V1 Auth Feature Priority Matrix
Here's a quick reference to help you decide what to include:
| Feature Category | Skip in V1 If... | Include in V1 If... | Add Later Difficulty |
|---|---|---|---|
| Email/password | Never skip | Always include | N/A |
| Password reset | Never skip | Always include | N/A |
| HTTPS | Never skip | Always include | N/A |
| Email verification | You don't send emails | You send important emails | ⭐ Easy |
| Social login (1 provider) | Users are enterprise-focused | Users are individuals/consumers | ⭐ Easy |
| MFA/2FA | Not handling sensitive data | Fintech, healthcare, crypto | ⭐ Easy |
| Enterprise SSO | No enterprise customers | Selling to enterprises now | ⭐ Easy |
| SCIM | Under 250-seat customers | IT department is buyer | ⭐⭐ Moderate |
| Multiple social logins | No demand data | You have analytics showing demand | ⭐ Easy |
| Passwordless | Standard B2B/SaaS | Less technical audience | ⭐ Easy |
| Custom domain | V1 launch | Never (low impact) | ⭐ Easy |
| Advanced analytics | Under 1K signups/month | Optimizing conversion | ⭐ Easy |
| Webhooks | No integrations needed | Building integrations now | ⭐⭐ Moderate |
| Bot protection | MVP stage | High-value target | ⭐-⭐⭐ Varies |
A Real V1 Auth Implementation
Here's what your V1 auth should actually look like in practice:
What Users See
- Signup page with email and password fields
- Optional: "Continue with Google" button (one social login only)
- Email confirmation sent (soft enforcement—doesn't block usage)
- Login page with email and password
- "Forgot password" link that sends reset email
Total screens: 2-3 (signup, login, password reset)
What You Configure
| Step | Time Estimate |
|---|---|
| 1. Set up auth provider account | 15 minutes |
| 2. Add API keys to your app | 15 minutes |
| 3. Implement login/signup forms | 2-4 hours |
| 4. Protect your authenticated routes | 1-2 hours |
| 5. Test the flows (happy path + errors) | 1-2 hours |
| Total implementation time | 4-8 hours |
This assumes a developer familiar with your stack and the provider's documentation.
What This Enables
✅ Users can create accounts ✅ Users can log in and out ✅ Sessions persist across visits ✅ Password resets work ✅ Optionally: Google sign-in as an alternative
What It Doesn't Enable (And That's Fine)
❌ MFA (users can't enable 2FA yet) ❌ Enterprise SSO (companies can't integrate Okta) ❌ GitHub login (only Google social auth) ❌ Webhooks (no events sent to external systems) ❌ Analytics dashboard (basic numbers only)
Result: You have working, secure authentication that lets users access your product. Everything else can be added incrementally based on real feedback, not speculation.
Feature Addition Timeline
Here's how features typically get added as you scale:
Months 0-3: MVP Launch
Features:
- Email/password
- Password reset
- One social login (Google)
- Basic session management
Why: Ship fast, validate product-market fit
Months 4-12: Early Traction (100-5,000 users)
Add based on requests:
- GitHub social login (if developer product)
- Email verification enforcement
- Basic webhooks (for onboarding automation)
Why: Solve real problems users report
Year 2: Growth (5,000-50,000 users)
Add for expansion:
- MFA (users requesting it for security)
- First enterprise SSO connection (sales requirement)
- Advanced analytics (optimization phase)
Why: Support upmarket movement, optimize conversion
Year 3+: Scale (50,000+ users)
Add for enterprise:
- SCIM provisioning
- Multiple SSO connections
- Advanced bot protection
- Custom domains
Why: Serve enterprise customers at scale
Planning for V2, V3, V4
The key to this approach is staying flexible and evidence-based. As you get feedback, keep a prioritized list:
User-Requested Features
Track feature requests with context:
| Feature | Requested By | Count | Priority | Revenue Impact |
|---|---|---|---|---|
| "Do you support MFA?" | 3 users | 3 | Medium | Low |
| "Can we SSO with Okta?" | Enterprise prospect | 1 | High | $50K/year deal |
| "Can I log in with GitHub?" | 12 users | 12 | Medium | Low |
Data-Driven Additions
Let analytics inform your roadmap:
- 78% of users choose Google login → Keep it, it's valuable
- 2% of users choose email/password → Consider making Google the default
- 0 users have enabled MFA → Don't prioritize building it yet
- 15% of signups fail email verification → Investigate email deliverability
Revenue-Driven Additions
Prioritize features that unblock revenue:
- Enterprise prospect worth $50K/year needs SSO → Add it this sprint
- No one asking for SCIM → Defer indefinitely
- 5 customers asking for Slack integration → Build webhook system for integrations
Let real usage inform your roadmap. Every feature you add later based on demand will be used. Every feature you add speculatively might not be—that's wasted engineering time.
Choosing a Provider That Grows With You
This entire strategy depends on picking an auth provider that makes it easy to add features later without major refactoring. When evaluating providers, check:
Can You Enable Features Without Code Changes?
- Good: "Enable SSO in dashboard, give customers metadata URL"
- Bad: "Email sales for SSO, then run a migration script and rebuild your app"
Are Features Available at Your Tier?
- Good: "MFA included in all plans, SSO on paid plans starting at $25/mo"
- Bad: "MFA requires Pro ($100/mo), SSO requires Enterprise (call sales)"
Can You Upgrade Gradually?
- Good: "Start free, upgrade to $25/mo when ready, add SSO for $50/mo"
- Bad: "Free tier, then jump to $500/mo Enterprise for any paid features"
Does the Provider Support Your Stack?
- Good: First-class SDKs for your framework (Next.js, Astro, SvelteKit), clear documentation, code examples
- Bad: Generic REST API, figure it out yourself, no TypeScript support
Provider Evaluation Checklist
- [ ] Features can be enabled/disabled without code deploys
- [ ] Pricing is transparent (no "contact sales" for basic features)
- [ ] Free tier is genuinely useful for MVP validation
- [ ] Upgrade path is gradual, not cliff-based
- [ ] Documentation is comprehensive and framework-specific
- [ ] Migration support if you need to switch later
AuthHero and the Growing-With-You Philosophy
This is why we built AuthHero the way we did:
- Essential features included in free tier: Email/password, social login (unlimited providers), session management, basic MFA
- Add-on features enabled with a click: SSO, advanced MFA, webhooks, custom domains
- No sales calls required: Self-service for everything up to 100K users
- Transparent pricing: You can see the cost of adding features before you need them
- Framework-agnostic: Works with Next.js, Astro, SvelteKit, vanilla JS—whatever you use
We want you to start simple and add complexity only when it makes sense for your business, not when marketing tells you to.
Conclusion: Ship Now, Enhance Later
Your MVP's job is to validate your core product idea, not to showcase your authentication system. Your users want your product—the problem you solve, the value you create. They don't care about your auth provider or feature list.
Every day spent building auth features is a day not spent on your core product. Every "nice to have" you add is another thing that can break, another configuration to test, another support question to answer.
Start With the Essentials
✅ Email/password authentication ✅ Password reset flow ✅ Optional: One social login (Google) ✅ Sessions managed by your provider
Then ship.
As users sign up and use your product, you'll get real feedback:
- "Can I use GitHub to log in?" → Add GitHub OAuth (30 minutes)
- "Do you support SSO?" → Enable SSO for that customer (2 hours)
- "I want 2FA" → Make it available as an opt-in (1 hour)
These features are easy to add when you need them. They're a waste of time when you don't.
The MVP Mindset
Ship your MVP. Get users. Listen to feedback. Add features that matter to real users experiencing real problems.
That's how you build something people actually want—not by guessing which auth features might matter someday.
Start with what you need. [Link: anchor text "Get started with our free tier →"] AuthHero's free tier includes everything on the "Essential" list—email/password auth, sessions, and basic security. Add more features when you're ready, no migration required.
