The Tectum XFA, or X-Factor Authentication, is a cutting-edge security measure used for password-free access to online accounts. It allows users to sign in to their personal accounts without the use of a standard password, by utilizing something only they know. This process is designed to be swift, safe, and user-friendly, and it does not require password memorization. Instead, a unique passcode is created by the user's handwriting. To use X-FA, a user needs to create an account, sign up for an online account, enable X-FA in the settings, and then they can start logging in with enhanced security.
