hello evryone i would like to know how can i add phone number in registration form, and how can I make login by (email or phone number)
You can enable the following option:
Studio > Settings > System > Account > Account is confirmed when > "phone is confirmed" or "email and phone are confirmed"
Then you need to setup Twilio:
Studio > Settings > System > Twilio
System will automatically ask for phone and send SMS for verification and will accept phone as login.
is there any other option then twilio. because twilio pricing is very costly.
