The value must be greater than or equal toRefresh token lifetimeWert.
The following diagram shows the lifetime behavior of the sliding refresh token window.
note

Can be used to perform authorization checks securely, such as when a token is used to access a resource. By default, the subject claim is populated with the user's object ID in the directory.
- A declaration representing the flow of users– This claim identifies the running user flow. Possible value:
tfp(Default) oracre.

Authorization code lifetime
When usingOAuth 2.0 authorization code expiredthe application can use the authorization code to request an access token for the target resource. Authorization codes are short-lived and expire after approximately 10 minutes. Authorization code expiration is not configurable. Make sure your app redeems the authorization codes within 10 minutes.
