Authy: 2FA and Passwordless Login


(warning)

Warning

As of November 2022, Twilio no longer provides support for Authy SMS/Voice-only customers. Customers who were also using Authy TOTP or Push prior to March 1, 2023 are still supported. The Authy API is now closed to new customers and will be fully deprecated in the future.

For new development, we encourage you to use the Verify v2 API.

Existing customers will not be impacted at this time until Authy API has reached End of Life. For more information about migration, see Migrating from Authy to Verify for SMS(link takes you to an external page).

The Authy app(link takes you to an external page) is our free application for time-based one-time passcodes. It's available for iOS, Android, macOS, Windows, and Linux.
