I have an implementation of web auth with Lock on my web application.
However I have a mobile app as well that provides additional services. It uses the same user base as the web. Users register on the web only before they get to interact with the mobile app.
What would be the best and maybe easiest way to implement authentication on the mobile side? I am not so happy with providing the web window option on the mobile side, prefer it to be in-app integration.
Is there some SMS based authentication, assuming I already registered the user and have his phone number?
Looking for a good approach that would also be simple enough to implement.
For example, I am less happy to fully implement all 3 customized options separately for login via username/password, Google, Facebook.
We use React-Native on the mobile ap part.
