Time-Based One-Time Password (TOTP) is a secure method for generating temporary passwords. It relies on the current time and a shared secret key between the user and the service provider. When a TOTP is generated, it typically changes every 30 seconds. The algorithm takes the current time and the secret key, producing a unique password that is valid only for that time window. This means even if someone intercepts the password, it becomes useless shortly after it is generated.Users often utilize TOTP through authentication apps like Google Authenticator or Authy. These apps create the time-sensitive codes necessary for logging in or approving transactions. This method enhances security by requiring not just a username and password, but also a TOTP, making unauthorized access much harder. Since each password is short-lived, the risk of theft is further minimized. Overall, TOTP adds a strong layer of protection against potential threats such as phishing or hacking.
