User has a custom attribute phoneNumber in Keycloak.
There is a default method for fetching token using username and password but would it be possible to authenticate using phoneNumber / password instead of username / password.
curl
-d “client_id=$CLIENT_ID” -d “client_secret=$CLIENT_SECRET”
-d “username=$UNAME” -d “password=$PASSWORD”
-d “grant_type=password”
“$KEYCLOAKHOST/auth/realms/$REALM/protocol/openid-connect/token”
What call should I use to authenticate using a custom attribute in UserModel
