- There are a number of different 2fa methods like OTP sent through email, sms, or biometrics but one of the most popular methods 2fa methods is TOTP.
- TOTP, or Time-based One-Time Password, is an algorithm that generates a unique, temporary passcode for authentication.
- TOTP stands for Time-based One-Time Passwords and is a common form of two factor authentication (2FA).
- The TOTP algorithm is tied to the current time. TOTP.APP will generate the correct one-time passwords only if the time on your device is set correctly.
- The Time-based One-Time Password algorithm (TOTP) is an algorithm capable of generating pseudo-random passwords through a shared private key.
- The TOTP algorithm follows an open standard documented in RFC 6238. The inputs include a shared secret key and the system time.
- The app can then generate TOTP values based on the current time. By default, a new TOTP value is generated every 30 seconds.
- One-time passwords, including TOTP, are a common possession or "something you have" factor and help increase the security of your users accounts.
- In this article, we will learn what OATH TOTP is. We will have a closer look at TOTP algorithm implementation and the work of the TOTP mode.
