ID tokens

During authentication, ID tokens carry information about authenticated users securely to your application.

ID token standard claims

Link to this section

• At hash - at_hash ensures the integrity of the claim made in the access token.
• Audience - intended recipient of the token. Represented as the token’s aud claim. This could be your kinde domain or app URI, e.g. https://<your_subdomain>.kinde.com
• Authentication time - auth_time indicates the time when the user was authenticated. It’s useful for scenarios where certain actions are allowed only if the user has recently authenticated.
• Authorized party - an azp claim specifies the client ID of the party to which the ID Token was originally issued.
• Email - the email associated with the user’s profile
• Expiration Time - The exp claim specifies the timestamp when the ID token expires and should no longer be considered valid. It helps prevent the token from being used indefinitely. More about setting token expiry in Kinde.
• Issued At - The iat claim indicates the timestamp when the ID token was issued. It can be used to determine the token’s age and to mitigate replay attacks.
• Issuer - The iss claim specifies the issuer of the ID token, usually the URL of the authorization server or identity provider. It’s used to verify the token’s authenticity.
• Picture URL - the picture claim contains the location reference of the avatar picture of the user, if there is one.
• Subject - The sub claim is a unique identifier for the authenticated user within the context of the issuing authentication server. In Kinde, this is the user’s ID.
• Token ID - the jti claim is the unique identifier of the ID token
• Updated at - the updated_at claim specifies the issuer of the ID token, usually the URL of the authorization server or identity provider. It’s used to verify the token’s authenticity.
• User last name - the family_name claim contains the user’s last name
• User first name - the given_name claim contains the user’s first name
• User full name - name contains the first name and last name of the user
