With Passage, your users will sign up and sign in with biometrics whenever possible. For example, iOS and macOS users will be prompted to use Touch ID or Face ID, Windows users will be prompted to use Windows Hello, etc. Biometrics offer a drastically better user experience than passwords or magic links, as they cannot be forgotten or mistyped, and do not require users to transfer their attention away from your application to click an SMS or email link. For devices that don't support biometrics, Passage automatically falls back to magic link authentication. In addition to the magic link, Passage will offer to enroll biometrics for any device where the link is clicked. In other words, Passage keeps track of all trusted devices and intelligently provides the smoothest login experience possible.
