  2. Read live 6-digit code plus countdown.
  3. Copy before it rotates; prefer phone apps for real accounts.

FAQ

Safe for real accounts?

It works, but prefer your phone app — browser tabs leak secrets more easily.

Clock matters?

Yes. TOTP derives from time — a skewed clock yields wrong codes.
