This revokes a refresh token at the OAuth provider. Leave the field blank to revoke the refresh token of your current session instead.
Existing logins may linger after revocation: tokens minted from the revoked token stop working within about an hour (when the local cache expires and the provider refuses to refresh them), but logged-in browser sessions are never rechecked against the provider, so they keep working until their session cookie expires (up to 14 days). Log out to end a browser session.
