I wrote about how to incentivize 2FA. The beauty of the Authy API is that no matter which method you use to send the token, you can check the tokens with the same API. What's next?Ĭongratulations on getting your users enrolled in 2FA! For more flexibility - check out the API docs for sending one-time passwords via SMS, voice, or even email. Learn more in the documentation for Authy one-time passwords. The Authy helper libraries for Python, Ruby, PHP, Node.js, and Java support this API call too. Alternatively if the user uses an Authy application token, the API response will include additional information available about their device. ![]() There's a lot of null data about the device, because we don't know anything about the device the user has. Register the user with the following command: You can find your Authy API key in the console under your Authy Application's settings tab: This example uses cURL, but you can do this in the language of your choice - see examples in more languages in the docs. Make a request to the Users resource to create a new user with the Authy API Key for your application. We'll walk through the example that uses PII here. There are two ways to add a user with the API: with and without PII. Registering users to your app using the Authy API You'll need your user's email address and phone number. Registering users to your app using the Twilio Authy Consoleįrom the Users tab of your Authy application in the console, click the red plus sign to add a new user.

Because the inputs are available offline, the whole method works offline. Those get put through a one-way function that creates a truncated, readable token. Inputs to the TOTP algorithm include a secret key and your system time.
