I have a Rocket chat custom (reskinned) web, iOS and android app.

I have done search can couldn’t find the answer

But I need to have it so that people MUST login to my app using their phone number and they MUST register using a phone number (email and password shouldn’t be enough). Custom fields aren’t that good for phone number. Can someone tell me what to do (or tell me what to tell a developer to do?

Hi!

You can try doing that by leveraging the [CREATE TOKENS API](https://developer.rocket.chat/reference/api/rest-api/endpoints/core-endpoints/users-endpoints/create-users-token)

Basically, you will handle auth your way, and once you get assert it can be authed, you will generate a token and redirect user to [http://chat.company.com/?resumeToken=received\_token](http://chat.company.com/?resumeToken=received_token)

let me know if this helps 🙂
