The Department of Revenue uses two-factor authentication when logging in.
- The first factor is the logon. The taxpayer will have a unique logon and password.
- The second factor is a six-digit code, which is sent to the taxpayer after he or she attempts to logon. This is accomplished via text, email, or both text and email.
- Taxpayers can then check a box that requests TNTAP to remember his or her device.
- Taxpayers can also opt out of two-factor authentication, although that is not recommended for security reasons.
