End-to-end testing two-factor authentication with SMS

Schedule a Demo

Two-factor authentication (2FA) refers to using a second measure beyond user name and password for verifying the identify of a user attempting to login. The most common methods of 2FA are email verification, text/SMS-based verification, or using an authentication application, otherwise known as an authenticator.

2FA with SMS is an essential part of building a secure application, but for a variety of reasons, it's also hard to test end-to-end:

  • Testing 2FA with SMS requires taking steps in multiple browser windows, or sometimes cross-device
  • If using tools like Selenium or Cypress, testing with SMS might require using complicated APIs

What's the easiest way to test 2FA with SMS?

walrus.ai enables engineers to test 2FA using SMS without any of the pain:

  • No need to handle the setup account details or credentials for SMS — walrus.ai handles that on their end
  • No integrating with complex SMS APIs
  • Writing the test takes minutes, because it's just plain English

A one-size-fits-most end-to-end test for 2FA with SMS using walrus.ai:

5 - 'Login'
6 - 'Verify a code is received via SMS'
7 - 'Enter the code and submit'
8 - 'Verify login is successful'

What does the result look like?
