Revoke Current Key

Stop the key this request is made with. Immediate, and the last thing it will do.

For a client signing out of a device that holds nothing but its own key. Revoking a key by its id refuses the one you are calling with, so that rotating can never leave you with none; this is that refusal lifted because you asked for exactly this.

It is refused while this is the account's only key and no sign-in is attached, because nothing could reach the account afterwards. Create another key first, or sign in.
