Authy: 2FA and Passwordless Login

For new development, we encourage you to use the Verify API instead of the Authy API. The Verify API is an evolution of the Authy API with continued support for SMS, voice, and email one-time passcodes, an improved developer experience and new features including:

  • Twilio helper libraries in JavaScript, Java, C#, Python, Ruby, and PHP
  • Access via the Twilio CLI
  • Improved Visibility and Insights
  • Push authentication SDK embeddable in your own application

You are currently viewing the Authy API. The Authy API will continue to be maintained, but any new features and development will be on the Verify API. Check out the FAQ for more information and Verify API Reference to get started.

Authy Helper Libraries

Instead of using the Authy API directly to integrate two-factor authentication into your app, we provide a helper library for common web languages. If your language is supported, it's the fastest way to get started.

API Reference

Authy consumer application

The Authy app is our free consumer application for time-based one-time passcodes. It's available for iOS, Android, and Desktop.
