Background
Why TOTP works.
Two-factor authentication adds a second layer on top of your password. TOTP generates a fresh 6-digit code every 30 seconds from a shared secret and the current time. Even if someone steals your password, they can’t log in without the current code.
FoxVault has a built-in TOTP authenticator that encrypts your 2FA secrets with per-item keys — so they’re as secure as the passwords they protect.
