Phone Verification after Apple Sign In

I signed in my user using apple Oauth now i wish to do phone verification so I am implementing this block of code

Future<void> updateAndVerifyPhoneNumber(String phone) async {

await appwrite.account
        .updatePhone(phone: phone, password: appwrite.user.password!);

await appwrite.account.createPhoneVerification();

  }

But I do not seem to get anything for the password of the user, I am aware one way is to take it in from the user, but since user signed in from Apple a password was not created.

what shall I do in this case

Okay shall I ask for the creation of a password first ?

that would make sense
