Pobox's software two-factor authentication uses Time-based One-Time Passwords (TOTP). Many applications support generating tokens using this format, including:
- Google Authenticator (for Android/iPhone/BlackBerry)
- Duo Mobile (for Android/iPhone)
- Authenticator (for Windows Phone 7)
- Authy (for Android/iOS/Blackberry)
- SGAuth
- 1Password
- LastPass
We also support the YubiKey hardware token's YubiKey OTP, which you can set up on this page. (We do not support FIDO at this time.)
