Authy

Two-factor authentication that keeps your accounts safe

Visit Authy

Authy is a free two-factor authentication app that adds a verification step beyond passwords for online accounts. Users scan QR codes from services such as Facebook, Amazon, Google, Microsoft and Dropbox to add tokens, then generate codes directly on their device. Tokens work offline, so logins to 2FA-secured sites remain possible without an internet connection.

Tokens sync across iOS and Android devices, including tablets and Apple Watch, and can be managed from the app, where users can view, rename or remove devices and disable future installations. Access can be protected with TouchID, PIN or a password, and new devices can be added via SMS, voice or approval from an existing device. Encrypted backups can be stored in Authy's cloud using a password that is never shared with Authy and cannot be recovered if forgotten.
