Force password reset flow

As an administrator, you can reset a user's password if the user forgets their password or you would like to force them to reset the password. In this policy sample, you'll learn how to force a password reset in these scenarios. It's the custom policy described at Set up a force password reset flow in Azure Active Directory B2C.

Live demo

To checkout the user experience of this policy, follow these steps:

  1. If you don't have an account, create a local account with your email address.

  2. Run the B2C_1A_Demo_SignUp_SignIn_ForcePasswordReset policy to check the value of the forceChangePasswordNextLogin claim. At this point it should be false. So, you don't need to reset the password.

  3. At this step you need to simulate a force password reset flow. Since you don't have access to the live demo tenant. We have prepared an helper policy that changes the value of the forceChangePasswordNextLogin to true. Run the B2C_1A_Demo_Helper_SignUp_SignIn_ForcePasswordReset policy. Sign-up or sign-in and provide a new password. This policy will simulate an admin changing the password for the user. Sign-in with the same account from step 1, and provide a new password. After you run this step, that account will be force to reset the password.

  4. Run the B2C_1A_Demo_SignUp_SignIn_ForcePasswordReset policy again. It will check the value of the forceChangePasswordNextLogin claim. This time it should be true and you must reset the password.

How it works

  • Claims:

    • continueOnPasswordExpiration - input claims of the login-NonInteractive technical profile. It instructs Azure AD B2C to continue upon password expiration.
    • forceChangePasswordNextLogin - output claims of the login-NonInteractive technical profile. It indicates whether the user needs to reset the password. If the value of this claim is true, other claims aren't return by the login-NonInteractive technical profile.

  • Technical profiles: -login-NonInteractive - The technical profile that validates the credentials. It customizes the one in the base policy, adding the input and output claims.

    • SelfAsserted-LocalAccountSignIn-Email - The technical profile that renders the sign-up and sign-in page. It customizes the one in the base policy, adding a call to the AAD-UserReadUsingSignInName technical profile to get the user attributes.
    • AAD-UserReadUsingSignInName - If the forceChangePasswordNextLogin claim is true, other claims don't return. So, it gets the user objectId by the sign-in name.
    • SelfAsserted-ForcePasswordReset-ExpiredPassword - Renders the password reset page. It calls the AAD-UserWritePasswordUsingObjectId-ResetNextLogin technical profile which persists the password to the use's profile.

  • User journey

    • SignUpOrSignIn_Custom - the precondition checks the value of the forceChangePasswordNextLogin claim and renders the password reset step.
