Two-factor authentication (2FA)
Requiring a second proof of identity in addition to a password: a code from an authenticator app, a hardware key, or a one-time code sent to the user. SMS is the weakest of these options.
Why it matters
Passwords leak in bulk from other services and are reused everywhere. 2FA is the single most effective measure against account takeover, which matters most for admin accounts and anything holding money.
How we approach it
We make 2FA mandatory for administrative access, offer app-based codes and passkeys rather than SMS where possible, and implement recovery carefully — a weak reset flow quietly cancels out the protection.
