What is the difference between 2FA API and tyntec’s OTP SMS API?

tyntec’s two-factor authentication (2FA) API enables your business to seamlessly capture and confirm your users’ phone numbers as part of the sign-up and 2FA processes. It is a feature-rich, programmable API that detects the phone number type (mobile or landline) and sends the passcode via the appropriate channel (SMS or text-to-speech).

In addition, tyntec’s 2FA API offers:

  • PIN generation, verification and expiration handling
  • The ability to customize language and sender ID to specific locales
  • Customized message and call templates, PIN length and time retry configuration
  • Pay per successful verifications.

At the same time, tyntec's SMS API enables you to send SMS messages globally. The SMS API can be used to send One Time Passwords (OTPs) globally, however it lacks verification features that assist companies in the 2FA process.

If your business has authentication capabilities in place and just need the OTP transmission, the SMS API can be ideal (though its business model is pay per message). In case your business prefers to get a verification service and/or requires a pay per successful verification, the 2FA API may be the best choice.
