What is 2FA and the benefits of using 2-Factor Authentication (2FA)?

2-Factor Authentication, or 2FA, requires users to verify their identity through two authentication methods to provide an additional layer of protection on top of inputting their username and password.

The most commonly used applications are Google Authentication and Microsoft Authentication.

2FA Benefits

Beyond username and password, users have one more security step to verify. 2FA generates a random 6-digit code, activated for only 30 seconds, making your accounts more secure.

📌 Do not delete the Authenticator application. It may result in the loss of all your 2FA-enabled accounts. You should also have 2FA on another device or keep the backup code in a safe place from where it can be recovered.
