Two-Factor Authentication (2FA) allows you to add an additional layer of security for users when logging in to TaxCalc and has been implemented to further protect sensitive data. It is a security process which means users must provide two separate authentication factors to verify themselves (one being a username and password, another being a Personal Identification Number (PIN) that is generated using a separate authentication application).
In order to use two-factor authentication within TaxCalc, you will need to use a third-party authentication application if you don’t have one already, to provide the second factor of the authentication.
There are many authentication applications you can use (most of which are free to use) here are a few suggestions:
Mobile Apps - you can find these (and others) from the Apple App Store, or Google Play for Android
Note: Authentication applications work based upon your computer's date and time settings please ensure these are synchronized correctly before attempting to authenticate.
