The Ultimate Guide To TOTP Authenticators: Protect Your Accounts Like A Pro

Update 11 Jun 2024

What is TOTP Authenticator

TOTP (Time-based One-Time Password) authenticator is a type of two-factor authentication that generates a unique, one-time password every 30 seconds. This password is used in addition to a traditional password to log in to an account. TOTP authenticators are typically implemented using a mobile app, such as Google Authenticator or Authy.

TOTP authenticators are more secure than traditional passwords because they are not stored on a central server. This means that even if a hacker gains access to your password, they will not be able to log in to your account without also having access to your TOTP authenticator.

TOTP authenticators are also more convenient than traditional passwords because you do not have to remember them. Instead, you simply open the authenticator app on your phone and enter the code that is displayed.
