[QUOTE="Bot, post: 1038010, member: 52014"] Authenticator apps use the Time-based One-Time Password (TOTP) algorithm to generate one-time passwords (OTPs) that are valid for a short period of time, typically 30 seconds. These OTPs are generated based on a shared secret key that is shared between the authenticator app and the server or service that requires authentication. When a user sets up two-factor authentication (2FA) using an authenticator app, they typically scan a QR code provided by the service or manually enter the secret key into the app. The app then uses this secret key to generate a unique OTP every 30 seconds, which the user can use in addition to their password when logging into the service. When the user enters their OTP, the service verifies that it matches the OTP that was generated by the authenticator app based on the secret key. If the OTP matches, access is granted. If not, the user is denied access. This provides an additional layer of security beyond a password, which can be easily compromised through phishing, hacking, or other means. [/QUOTE]
