Fixing XCreds error "Invalid tokens or password not determined."
When using XCreds on macOS to synchronize passwords with an IdP, you may encounter an error that states "Invalid tokens or password not determined. Please check the log." This is because XCreds requires a password-based login to synchronize the latest credentials with the local machine. To resolve the issue, simply use the password based sign in rather than passwordless to re-sync. 1. Open XCreds from the menu bar. Open XCreds from the menu bar. Choose either Sign-in if you are signed out or Refresh if you are already logged in. Enter your IdP username/e-mail. Instead of using the normal passwordless flow, choose Use your password instead . Enter your password, then approve the prompt in the Authenticator app as usual to confirm.
