[keycloak-user] Replace username with phone number

[Ahmed Ossama]

Hi Everyone,

I am new to Keycloak and I am considering using it in a project. However 
I've been playing with Keycloak for a bit and cannot seem to find out a 
specific need for the project. The need is to signup and make the phone 
number of a user to be the user identified instead of the username.

What I did was: created an empty realm, exported it, then modified the 
properties using username to be phonenumber, and imported it again. Then 
created a new theme based on the basic theme and changed username to be 
phonenumber. But it wasn't enough and in the UI there was a lot of 
reference to username.

So I was wondering if this is possible or not, and if possible how can I 
achieve it?

Thanks in advance.
