Adding SMS Auth to your mobile app (TLDR)
App and data security have been a big issue for developers for a while now and it’s only getting more important. Below is the TLDR version and here is the extended version.
What is two-factor SMS authentication (2FA)?
SMS Two Factor Authentication (2FA) is a security verification procedure that allows a company to more safely identify their users.
Automate SMS authentication integration with 46elks
Using the 46elks API to add OTP means you can implement authentication processes in the way your team wants them to. Here are the basic building blocks to adding SMS OTP authentication to your mobile app:
- Create a 46elks account - Sign up
- Create a database to record the expected OTPs and user information
- Create a trigger in your application that does two things:
- Generate an OTP and add it to the database along with the appropriate user information (and time if necessary)
- Sends an SMS to the customer with the same OTP using the 46elks API
- If it matches then you can allow entry
- If it does not match then you can offer reattempts or simply deny the service
These are the broad building blocks and depending on your application you may need to tweak this flow slightly to provide your users with a great experience and secure your applications.
