Two Factor Authentication

Two Factor Authentication

Add Two Factor Authentication features using Sinch

More business are using Two Factor Authentication in their applications to verify users and personal account information. This adds a secure layer between a users password and their account data.

Typically, Two Factor Authentication relies on your backend generating a random, unique code for the user, sending this via SMS to the users mobile phone and verifying this code once entered. This combination of password and random, one time code makes user accounts much safer.

The Sinch SDK can be used to deal with the SMS, taking a request from your backend and sending the SMS to the user in real time. With our simple REST API, Sinch can deliver your Two Step Verification SMS to more than 100 countries.
