So the best way to think this system is having not one but multiple locked doors guarding your home, so even if one of the keys is lost, anyone who finds the key still would not be able to get into your house. ![]() For a service protected by multi-factor authentication, a password alone still would not provide access. This also protects against risks where your password is leaked through a hack. But since T-OTP are only valid once and only for 30 seconds, even if they recorded your T-OTP, it would be useless after you used it yourself. For example, if you are recorded by a CCTV or other camera typing in your password, it would have been compromised. This adds a significant level of improvement as an adversary no longer just needs your password, they also would need to get access to your second factor in order to log in. The service which is asking you to provide your T-OTP will know which T-OTP is valid, so once you provide a password as the first factor, and the T-OTP as the second factor you would be logged in. An authenticator generates Timed-One Time Passwords (T-OTP) and typically refresh every 30 seconds. While these factors offer some additional security, they are not as strong as using an authenticator app. Typically, a password is the first factor, and the second factor would to be something else, like clicking a link in an email, or typing in a code from you received in a text message. Services like Microsoft 365, Google Workspaces, Bitwarden, Gmail, Facebook, Twitter, Slack, WhatsApp can all be setup to require a second factor log in.
