What is Google Authenticator?

Google Authenticator is a software token that implements two-step verification services using the Time-based One-time Password Algorithm (TOTP) and HMAC-based One-time Password Algorithm (HOTP). It generates a six to eight-digit one-time password which users must enter in addition to their regular password when logging into their accounts.

How does Google Authenticator work?

Google Authenticator works by generating a new six to eight-digit one-time password every 30 seconds. This password is unique to each user and account, providing an extra layer of security beyond just a username and password. Users must enter this code along with their regular credentials to access their accounts.

Why use Google Authenticator?

Google Authenticator adds an extra layer of security to your accounts by requiring a second form of verification beyond just a password. This helps protect against unauthorized access, phishing attacks, and other security threats. It is easy to use and can be set up quickly for added peace of mind.
