Hello, I want to make the user log in with his phone number as nickname and a password. So when he creates his account, he enters his phone number, verifies his phone number with an OTP code by sms and completes his registration. To log in, he enters his phone number and password. In other words, he doesn't receive an OTP code every time he wants to connect, but only once when the account is created, to verify his number.
The Auth system with firebase apparently doesn't allow this. I'd be happy to get help with this.
Thanks in advance
