Token decoder
Paste a Trustaige ID token, access token or Security Event Token to see every claim, what it means, and whether the signature checks out.
The token never leaves this page. Verifying fetches only the issuer's public keys.
What your app should check
Decoding shows what a token says; it proves nothing. Before you trust an ID token, your server checks the signature against the issuer's keys, that
iss is the issuer you configured, that aud is your client ID, that exp has not passed, and that
nonce matches the one you sent. Use your platform's OpenID Connect library rather than writing these checks yourself.
