Fixing Expired Passcode B2C Azure Issues with Azure AD

Expired passcode issues in B2C Azure can be frustrating, especially when they prevent users from logging in. This problem often arises from a mismatch between the Azure AD and B2C passcodes.

To resolve this, you need to synchronize the passcodes in both systems. This can be done by updating the Azure AD passcode to match the B2C passcode.

However, if the passcode has expired, you'll need to reset it first. This involves generating a new passcode in Azure AD, which will then be synced with B2C.

Once the passcode is reset, you can update the Azure AD passcode to match the new B2C passcode. This ensures that both systems are in sync, allowing users to log in successfully.

Azure AD Password Settings are crucial to maintaining a secure environment for your users. By default, password expiration is disabled in Office 365, but you can still enable it for your tenant.

To enable password expiration, you'll need to access the Microsoft 365 admin center. Once you're there, follow these steps: Open Settings > Org settings, click on the Security & Privacy tab, and then open the Password Expiration Policy.

You can set user passwords to expire after a number of days, and optionally change the number of days before the password expires and the notification. Simply enable the "Set user passwords to expire after a number of days" option and click Save to apply the settings.

If you want to force a password reset after 90 days, you can use MS Graph to set the user's password expiration to 90 days. This will automatically set the value of the forceChangePasswordNextSignIn attribute to true.

Here's a step-by-step guide to update the password policy to None, which forces a password reset after 90 days:

Alternatively, you can use the Update-MgDomain cmdlet from the Microsoft Graph PowerShell module to update the tenant so that all users' passwords expire after a number of days you configure. This command updates the password validity period in days, which is the length of time in days that a password remains valid before it must be changed.

Enabling password expiration is a crucial step in maintaining account security. By default, password expiration is disabled in Office 365, but you can still enable it for your tenant.

To enable password expiration, you'll need to access the Microsoft 365 admin center, where you can open the Settings > Org settings and click on the Security & Privacy tab.

Once you're there, you can open the Password Expiration Policy and enable the "Set user passwords to expire after a number of days" option.

You can also optionally change the number of days before the password expires and the notification. After making your changes, be sure to click Save to apply the settings.

If you want to force a password reset after 90 days, you can use the MS Graph to set the user's password expiration to 90 days. This will automatically set the forceChangePasswordNextSignIn attribute to true, requiring the user to reset their password.

To do this, you'll need to remove the DisablePasswordExpiration value from the user's profile Password policy attribute. This will update the password policy to None, forcing a password reset after 90 days.

Here are the steps to update the password policy:
