More security. Less hassle.
For frictionless authentication, send a push notification directly to your user’s device, alerting them that an authentication attempt is taking place. Users will have the option to view authentication details and approve or deny access with a single touch. Communication between the user’s smartphone and Authy is encrypted end-to-end and cryptographically signed. It’s our simplest, and strongest authentication offering.
