How to use Google Firebase phone authentication in ionic App , I tried many plugins and even bought one and still didn’t find something working
Greetings, I leave you the link with the documentation of what you need. I recommend that you read it and be able to interpret it in a better way so that when you are coding and it is not for some reason you can tell us in a better way which version of ionic you are using, version of cordova and part of the code that you are doing in order to give you a better help or even a solution to the problem, for the moment I can only leave the link with the official documentation and do not provide more information about it. I remain attentive to your comments
In case you haven’t solved it, this tutorial helped me (Android only, not working in iOS so far) https://medium.com/@gbrigens/ionic-3-phone-authentication-with-firebase-dbed967e95ef.
