After writing about modern credential management, we would like to get an impression of your usage of 2FA. What do you use for two-factor authentication? Do you use two-factor authentication at all, or even multi-factor authentication?
- SMS-based one-time password
- app-based one-time password (e.g. using FreeOTP)
- token-based one-time password (e.g. using a YubiKey)
- U2F (Universal 2nd Factor)
- Others (please write a comment)
