      Article summary

      Biometric login (e.g., fingerprint or facial recognition) provides a streamlined login process. The Mapp Intelligence SDK allows you to track events when a biometric login is successful or failed.

      • Email Login: Tracks user logins using username and password, sending a tracking event when the input is valid.

      • Biometric Login: Tracks user logins using biometric data (e.g., fingerprint, facial recognition), sending tracking events for successful or failed logins.

      Due to technical restrictions, it is difficult to distinguish the type of device recognition used. It is possible to detect the preferred login type, though.
