Choose a path
Understand authentication
See how Authie owns browser sessions while application servers verify short-lived, scoped session tokens.
Read the authentication model →Understand the credentials
See exactly which values belong in the browser, on your backend, or only in a provisioning tool.
Learn the token model →Manage application users
Use the server-only Backend API for users, invitations, sessions, roles, and private metadata.
Use the Backend API →Hand the job to Codex

Use Authie with Codex →The model in one minute
Identity is shared
A person can use one Authie identity across products you operate.
Access is isolated
Membership, disabled status, sessions, tokens, and subscription state remain scoped to one application.
Authie handles login
The SDK uses Authie's Frontend API for hosted or embedded authentication and session continuity.
Authorization stays scoped
Authie supplies application roles and permissions; your application retains its product and domain authorization.
