What is Two-Factor Authentication (2FA)?
Two-Factor Authentication (2FA) is a critical security measure that adds an extra layer of protection to your online accounts. It requires two different forms of verification - typically something you know (password) and something you have (your mobile device or this authenticator).
How Does TOTP Work?
TOTP (Time-based One-Time Password) uses a secret key and the current time to generate a unique, 6-digit code. These codes refresh every 30 seconds, making them virtually impossible to guess or intercept.
