Keycloak (Quarkus 21.x.x) Phone Provider

• Phone support like e-mail
• One Time Password (OTP) by phone
• Login by phone
• Register with phone
• Authentication by phone
• Reset password by phone

sms
voice
phone one key login

With this provider you can enforce authentication policies based on a verification token sent to users’ mobile phones.
Currently, there are implementations for:

• Aliyun
• AWS SNS
• Cloopen
• Tencent
• TotalVoice
• Twilio,
• YunTongXun SMS

More services can be added with ease due to the modularity of the code. In fact, nothing would stop you from implementing a
sender of TTS calls or WhatsApp messages.

This is what you can do for now:

• Check ownership of a phone number (Forms and Rest API)
• Use SMS as second factor in 2FA method (Browser flow)
• Login by phone (Browser flow)
• Reset Password by phone
• Authentication by phone (Rest API)
• Authenticate everybody by phone, auto create user on Grant (Rest API)
• Register with phone
• Register only phone (username is phone number)
• Register add user attribute with redirect_uri params

Compatibility

This was initially developed using Quarkus Keycloak as baseline. Wildfily keycloak is not supported
anymore and I did not test user storage beyond Kerberos or LDAP. I may try to help you but I cannot guarantee.

Theme

You will need to change the realm login theme to phone.

You can create a customized theme base on phone.

  parent=phone

Phone registration support

Two user attributes are going to be used by this provider: phoneNumberVerified (bool) and phoneNumber (str). Multiple
users can have the same phoneNumber, but only one of them will have phoneNumberVerified = true at the end of a
verification process. This accommodates the use case of pre-paid numbers that get recycled if inactive for too much time.

Thanks

Some code written is based on existing ones in these two projects: keycloak-sms-provider
and keycloak-phone-authenticator. Certainly I would have many problems
coding all those providers blindly. Thank you!
