About Replit Auth

Replit Auth is authentication built into Replit Apps. It can be switched on for an app rather than built, and Replit handles the sign-in screens, sessions, and user records, so an app gets working login without an auth library, database table, or third-party service.

End users can sign in with Google, GitHub, X, Apple, or email, and each sign-in creates or reuses a Replit account. The app owner chooses which login methods to show and sets the app name and icon on the login page. The Auth pane lists every signed-in user, shows their details, and can ban users from the app.

Once enabled, Replit passes verified identity headers (email, user ID, profile info) to every request, so any backend language or framework running on Replit can read the signed-in user without installing an SDK. That simplicity is also the constraint: verification happens at the platform's edge, so Replit Auth cannot be added to a backend hosted anywhere else, and apps that move off Replit need a dedicated auth provider instead.

Key Features

Login switched on per app with no auth code to write
Sign-in with Google, GitHub, X, Apple, or email
Choice of login methods plus app name and icon on the login page
Verified identity headers passed to every request
Auth pane to view users, see details, and ban users
Works with any backend language running on Replit

Pros

Turned on per app, with no auth code, database, or third-party service to wire up
Common social and email sign-in methods without configuring OAuth apps
Identity arrives as verified request headers, so any backend can read it

Cons

Every end user ends up with a Replit account, which some audiences will find odd
No SSO, custom identity providers, or fine-grained auth flows
Only works for apps served from Replit; not usable once hosting moves elsewhere
