# Issue a new set of backup codes

> Replaces every backup code with 10 new ones. Requires a live authenticator code — a backup code won't do, so one leaked code plus a stolen session can't mint more. A wrong code is 403. Rate-limited to 10 requests per 15 minutes per IP. Writes a REGENERATE_BACKUP_CODES audit entry.
