Inspect OAuth and OpenID Connect Tokens
Decode access tokens, ID tokens, and refresh tokens from Google, Auth0, Okta, Microsoft, and other OAuth providers.
🔒 The token is decoded entirely in your browser. Nothing is sent to any server.
OAuth / OIDC tips
ID tokens contain user identity claims (`sub`, `email`, `name`). Access tokens contain authorization claims (`scope`, `roles`). They serve different purposes.
For Google OAuth tokens, the `email_verified` claim is essential — never trust the `email` claim without verifying this is `true`.
Auth0 and Okta tokens use custom claims with namespace URLs (e.g., `https://yourapp.com/roles`). These appear in the payload but aren't standard claims.
Microsoft Entra (Azure AD) tokens have specific claims like `tid` (tenant ID), `oid` (object ID), and `appid` — see them clearly in the decoded payload.
