About Replit Auth
Replit Auth is authentication built into Replit Apps. It is 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, a database table, or a third-party service.
End users sign in with Google, GitHub, X, Apple, or email through a login page hosted by Replit, and each sign-in creates or reuses a Replit account. The app owner chooses which login methods to show, and the Auth pane lists every signed-in user, shows their details, and can ban users from the app. It works across development URLs, published apps, and custom domains.
The only supported way to add it is through Replit Agent: the docs state that manual implementation is not supported. That keeps setup to a prompt, but it also ties login to Replit's platform and to how Agent wires it in, so an app that moves off Replit would need a dedicated auth provider instead.

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
- Built-in user list and ban controls in the Auth pane
Cons
- Every end user ends up with a Replit account, which some audiences will find odd
- Limited to the five listed login methods, with no custom identity providers documented
- Can only be set up through Agent, since manual implementation is not supported
- Tied to Replit, so apps that move elsewhere need a separate auth provider
