Webflow does not natively support user authentication (logins) beyond Webflow Memberships, and even then, it's limited in terms of complex user management and integrations.
1. Use Webflow Memberships (Native Option)
- Webflow Memberships lets you build gated content and user login functionality directly in Webflow.
- It supports user sign-up, login/logout, protected pages, and role-based content.
- As of 2024, it includes custom fields, user profiles, and limited CMS integration.
- Limitations:
- No advanced access control (e.g., complex permission sets)
- Not suitable for apps requiring real-time syncing or complex backend logic
- Payment systems (like Stripe) are available but limited to basic plans
2. Confirm Compatibility with Existing Software
- If your existing software relies on external APIs, user-specific data, or server-side processing, Webflow alone may not support it natively.
- Webflow Memberships doesn't offer server code execution, database joins, or deep integrations with external authentication protocols (e.g., OAuth, LDAP).
- Ensure that using Webflow Memberships won’t break existing integrations — especially if you’re replacing Firebase's role in providing user authentication and session management.
3. Consider Workarounds if Needed
If Webflow Memberships is too limited, but you want to avoid code or heavy third-party tools, consider:
- Memberstack: Seamless integration over Webflow’s frontend with more flexibility than Webflow Memberships.
- Outseta or Auth0 with no-code bridges: Advanced login flows with support for existing data and APIs.
4. Preserve Existing Functionality
- Maintaining your existing software and features depends on how tightly they’re coupled with Firebase.
- If your system uses authenticated API calls with tokens or real-time data sync, Webflow alone can’t replicate that.
- You may need to build a hybrid system, where Webflow handles UI and display, and a backend (possibly still using Firebase or another service) manages secure logic and data.
Summary
Webflow Memberships allows you to create basic login functionality natively, but it comes with important limitations. For anything beyond simple gated content, consider hybrid approaches or light third-party tools like Memberstack to ensure compatibility with your existing systems.
