![]() ![]() 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. "Multi-Factor Authentication" simply means that you use at least two ( multiple) ways ( factors) of letting systems know that you are who you say you are ( authentication). □ Setup an Authenticator for Multi Factor Authentication TYPE
