How to enable password reset from Windows 10 login screen – Mobile-First Cloud-First

In Windows 10 1709 there is a lot of new feature – one of them is enabling of password reset from the user login prompt. We all know of users that have been on a long weekend or a vacation the first think they do when they come back to work is to call the servicedesk to help reset there password. Password reset is a part of AzureAD P1, in the past the user need to go into another devices then the one where the need to login to – start a webbrowser and go to the AzureAD Password Selfservice Portal. Now Microsoft has done it a lot easier for the user, by getting a password reset link inside the login GINA – all you need to do is enable it.

In this blog post I will cover how to enable it with Intune MDM, and not how to setup and configure AzureAD password reset backend service.

Requirement:

  •  AzureAD Password reset is configured
  • Running Windows 10 1709

Start by creating a custom Windows 10 profile in Intune

In this Windows 10 custom profile ‘ I have created 2 OMA-URI Settings – one for Password reset and one for PIN reset (PIN reset is working from Windows 10 1703)

  1. Name: Self-Service Password Reset from Lock Screen
  2. OMA-URI: ./Vendor/MSFT/Policy/Config/Authentication/AllowAadPasswordReset
  3. Data type: Integer
  4. Value: 1

If you want to tryout the PIN reset here is the settings

  1. Name: EnablePinRecovery
  2. OMA-URI: ./Device/Vendor/MSFT/PassportForWork/[TenantID]/Policies/EnablePinRecovery
  3. Data type: Boolean
  4. Value: True

Then you have a profile in Intune you can assign to your users or devices

How does this looks like from a user perspective:

The user is starting their device and have forgot the password.

The user clicks on the “Reset password” Windows GINA is redirecting to the AzureAD Password reset service

The user ID is password along – the user clicks next

The user can choose what verification method they what to use.

In my example it is a text to my mobile phone – so the user need to enter the text send to the mobile phone and click next

The user gets a verification code on there phone and enter the code and click next

Now the user can create a new password and click next

The user password has now been reset without calling the servicedesk for help

Windows now returns to the login GINA again and the user can login and be productive

Everything in Intune can be created by powershell via the Microsoft Graph API today so here is the script to do it.
