Flexible Security For Your Peace of Mind

Finding Active Directory passwords set to never expire

(Last updated on September 23, 2020)

Passwords set to never expire can be a security vulnerability for your network.

Some regulatory bodies require passwords to expire every 90 days, while others recommend setting passwords to never expire – as long as other protocols are in place. However, if you don’t have those in place or if you didn’t intentionally set passwords to never expire, you may want check your Active Directory for any instances of the setting.

Find AD passwords set to never expire with PowerShell

One way to do this is with PowerShell.

If you’re a PowerShell user and have the Active Directory PowerShell module installed, you can use the below line to find users with the PasswordNeverExpires attribute set to true:

get-aduser -filter { passwordNeverExpires -eq $true  -and enabled -eq $true } | sort | ft

Which will return a screen of results like this:

If you’re not a PowerShell user, or simply aren’t in the mood for it, you can also find which of your Active Directory users have passwords that are set to never expire with Specops Password Auditor.

And export to CSV if desired.

What to Do About Passwords That Never Expire

Once you’ve found out which Active Directory users have passwords set to never expire, the next action is to decide what to do with them.

Have you set these intentionally? Great. Then your next step would be to ensure that these passwords are not passwords that are known to be breached.

If you’ve got known breached passwords active in your environment, you’ll want to look at blocking those – whether you go DIY or with Specops Password Policy which can block over 2 billion known breached passwords with Breached Password Protection.
