service.jwt.is_revocable (legacy)
The current plugin does not read this ConfigPress key. Token issuance defaults to a revocable token and accepts revocable in the per-token settings array.
$token = AAM::api()->user(42)->jwts()->issue([], ['revocable' => false]);
This creates one non-revocable token for user 42. Use that setting only when the token lifecycle requires it. See the ConfigPress reference for active keys.
