Disable password expiration notification in browsers

[Jakob Rohde]

Many users are complaining over the password expiration popup message in the Office 365 portal. Our users' accounts are synchronized from AD so it is Windows 10 that manages password reset.

Is it somehow possible to disable the password expiration notification in browsers?

In the admin center (admin.microsoft.com), go to the Settings > Settings.

Go to the Security & privacy page. If you aren't a global admin, you won't see the Security and privacy option.

Select Password expiration policy.
Select the checkbox to not expire the passwords. This should prevent the password expiration in the browsers.
