What is Google Authenticator?

Google Authenticator is a mobile app developed by Google that provides an additional layer of security for your online accounts. It is part of a two-factor authentication (2FA) system, which adds an extra step to the login process to verify your identity. Google Authenticator generates 6 digit codes to add an extra security layer before users gain access to a business system. The generated code periodically changes and nobody who does not have the code can access to the account.
