    Local account password change results in cascade of oddball issues


    All

    Like any responsible Windows user - I change my password for my personal PC (and that same account on about 10 other workgroup PCs) usually once per year.

    Yesterday was password change day and I used ManageEngine Endpoint Central to schedule the change across 10 PC (A mix of physical and VMs). Change went fine. Since I initiated the change from my personal PC - I immediately logged off and back on using the new password - and all was well. Or so I thought....

    As soon as my PC logged in - OneDrive started complaining that it could not connect and that I had to perform an MFA/2FA sequence to "relogin" to One Drive.

    Then Outlook 2019 (Office 2019 Pro Plus edition) started complaining that BOTH of my MS accts (one Outlook.com acct AND my Office 365 Business acct) needed to be relogged into - which turned into a nightmare that took 4 hours AND a call to MS 365 support to look into. For one of my Office 365 accts - it took me about 2 hours just to add the 365 email account back into Outlook 2019.

    Then my "work" Office 365 acct started acting weird and I had to do another MFA on that to get it right.

    Then a while later seemingly random websites suddenly needed a relogin. LastPass suddenly threw up its Master Password dialog and on and on. Felt like I dumped my Edge cache completely and had to relogin into every website I ever went to in order to reset cookies.

    To top it all off - the TPM module (tpm.msc) started to throw an error like its driver had disappeared and that took another 15 minutes to settle down.

    I finally deleted ALL the Work/School accts from both Office 365 access points and readded them and that finally seemed to get things settled down.

    All in all - a total waste of a Sunday - all due to a password change on my local account to login to this machine? I am wracking my brains to try and associate how just ONE of these issues could be related to a simple password change but all of them seem a tad farfetched. Even the Tier 2 MS Support guy was surprised to see such a cascade of problems start from this.

    Anyone else ever had anything like this happen before OR does anyone have any idea how a local password could mess with MS MFA/Authenticator and completely bake all my accts in an instant.

    I would have thought that a local acct is just that - a local account that has no bearing on anything except to login to a machine access it's normal resources and carry on just like it did with its old password - which worked perfectly for months.

    If this is what I am going to get everytime after a simple password change - this will be the last one I do.

    Interested to hear any other stories on this.

    Cheers!

    Microsoft says mandatory password changing is “ancient and obsolete” - AT

    True dat. I get it.

    But - not really interested in the "right or wrong" part of this. Really wanted to get a sense if what I saw here was the result of the mind-boggling possibility that something as benign as changing my lowly Windows local account password could be so juiced into a ton of other important stuff that will instantly break if a change occurs.

    If this is true - it is so far from ancient and obsolete - it's not even funny. It's actually dangerous as a change like this (in the wrong hands - like say Grandma who lives 300 miles away on the farm) ends up completely botching a machine so you can't even get into it (or a master MS Account) or some other unexpected headache.
