The major reason behind Time-based one-time password (TOTP) is a computer algorithm that generates a one-time password (OTP) using the current time as a source of uniqueness. This is useful if totp is being used on a machine with the incorrect time. SMS OTP sends the passcode to the user's Time-Based One-Time Password (TOTP) The time-based one-time password (TOTP) secret key/seed is static just like the HOTP, but the moving factor in TOTP is time-based (hence the name). The one major downside of TOTP is that the secret key is stored on both the user’s device and the server.

The time-based one-time password improves upon another authentication protocol called the HMAC-OTP or the hash-based message authentication code – OTP algorithm. TOTP generates a temporary six-digit code that changes every 30 seconds, providing an additional layer Generating a Time-Based One-Time Password (TOTP) secret is the initial step in setting up two-factor authentication (2FA) for your web application. If you lose access to your authentication device, you can use your TOTP app backup to access your authentication method and account credentials on a different authentication device, ensuring continued access to your 2FA-enabled account.
