Authentication settings vary by platform and must match the application type.
Platform Configuration Overview
| Platform | Configuration |
|---|---|
| Web | Redirect URI, sign-out URL, token settings. |
| Single-page application | Redirect URI, authorization code flow with PKCE. |
| iOS / macOS | Bundle ID, auto-generated redirect URI. |
| Android | Package name and signature hash. |
| Mobile and desktop apps | Suggested or custom redirect URIs. |
Redirect URI Security Requirements
Use HTTPS, except for localhost during development.
Match case exactly.
Follow strict trailing slash rules.
Avoid unsupported special characters.
Incorrect redirect URIs are a common cause of authentication failures.
