After I changed password iterations to 600000, my master password would not work.

After receiving the security bulletin, I changed my password iterations from 5000 to 600000.  I was able to login with my master password as part of the change process, but afterwards, when attempting to edit my credit card information, my master password was not accepted.

Next, I "reverted" to the my last master password.  That worked but my iterations also reverted to 5000.

When you "reverted" your password, did it just keep the same current password you had been using, since you didn't actually change your password?  Or did you have to remember what your previous password was, which may have been something from some time ago?

**bleep** you lucky.... i'm unable to revert my password... they said my accound doesn't exist... since i updated the Iteration to 600 000.... -_-

Fortunately, it reverted to the password I was using. Not sure if I would have been able to dredge up the one I had prior to that.

Thank you so much for your reply, it's very helpful.

**FIXED**

I finally got a call back and fixed the problem. Hope it works for you.

It involved clearing caches on both LastPass and Chrome. Not sure which was the fix but suspect it was Chrome as accessing LastPass through Incognito mode already didn't have this problem.

Clear LastPass cache:

1) Open the Chrome extension and click the Account icon at the bottom right

2) Click "Fix Problem Yourself", first row

3) Click Clear Local Data, then click Refresh Vault. No popup, just an icon animation.

Clear Chrome browsing data:

- Well you guys all know how to do this...

Good luck.

I'll give the "Fix" a try and let everyone know whether it worked for me.  Although the process should be quick, I want to make sure I have some time on my hands before trying it -- just in case I have problems.  So it may be a day or two before I get a chance to do it.

The fix worked

Unfortunately, the problem returned the next day.  Again, I had to revert my master password.  And again, the iterations returned to 5000.

Kind of frustrating.

I am having exactly the same problem.  The master password doesn't work on my desktop but it does work on my Android phone so I don't know what is going on.

If I go to my Account Settings in my desktop, then under Login Credentials, then Master Password - it says that I changed my LastPass master password on March 2, 2023. I definitely did not change my master password as I was able to access it only yesterday but I think I changed my iteration value to 600000 on March 2 so I wonder if that is causing all the problems.  Maybe it's better to revert your password and let LastPass automatically update the iteration value to 600000  as in their  Security Bulletin it states that "all existing accounts will be upgraded automatically to meet the new minimum value (no customer action required)"
