All AD B2C users with local account and email signup to get otp in their phone number also.

Question

In our ADB2C , we have given email login and verification code is sent to email address. The user-flows are default.
Now many users forgot password of their email address so they are not able to create account or reset password in our app.
We are collecting user phone number as part of user-signup.

Hi @Ayan Patranabis • Thank you for reaching out.

You can receive OTP for sign-in only when you have signed up using Phone Number. If you have signed-up using Email Address and collected phone as part of sign-up process, you will not be able to sign-in using phone number.

Best you can do is, configure Self Service password reset for the users by configuring below settings:

1. In the Azure portal > Azure AD B2C > Select User flows > Select a sign-up or sign-in user flow (of type Recommended) that you want to customize > Select Properties > Under Password configuration, select Self-service password reset > Save
2. Under Customize in the left menu > select Page layouts > In the Page Layout Version, choose 2.1.3 or above.
3. Once above settings are configured, users can reset their passwords by clicking on "Forgot your password?" link on the sign in page.
