To use two-factor authentication, a User must have the following ready:
- an authenticating device: this is usually a personal device the User has access to during the login process, e.g., their smartphone,
- an authenticator app installed on their authenticating device.
There are a number of third party Authenticator apps available and free that Users can easily download to their personal devices. Some popular ones are Authy, Microsoft Authenticator, and Google Authenticator.
NOTE - The authenticating procedure may vary slightly for different apps but they all involve the scanning of a QR Code or manually entering an entry key, and then obtaining the authentication PIN for login.
