Unable to change password for other user as Admin Currently using an Admin account on my MacBook Pro 2019 running macOS Monterey and trying to access other (standard) account because I can't seem to login (password for that account literally just sopped working after messing with GeneratedUID from this link: **** I need to access that account for some files and every time I try to change the password of that account using my Admin account through system preferences I get hit with "Reset password failed." Trying to do it through terminal its: "passwd: Authentication server failed to complete the requested operation. Authentication server failed to complete the requested operation." Is there any way to get into that account or recover some files at all? [Personal Information Edited by Moderator]

I changed my admin user name and now my mac won't accept any name or password for admin changes. I use high sierra; I changed my administrator username, clicked the lock and then restarted my computer. It no longer shows a user name in that box and doesn't accept any username or password that I put in, even though I can still log into the computer under my original username and password. I'm no longer recognized as an administrator or technically a user...HELP!!!

Reset user password on new macbook pro now cannot login to admin Hi there, I purchased a 2nd hand macbook, and logged in with User and password all going perfectly. To personalise it, I changed the password, through System Preferences and Users. Clicking the lock to make changes. That worked. I then thought to change the user to my name, and clicked lock to make changes, entered personal password, still with Username from purchase. I right clicked on the User, and it gave me advanced options, which I clicked on, and I had the fields to fill in to change. So I changed this to my name and new password. this is where the difficulty came. I can login to the screen at the beginning of switching on. However, I was downloading garageband, and it wanted the admin username and password. There is only the one username and password I have used, which was the admin one in the first place. It now doesn't recognise this. I also had the same issue with downloading firefox, it asked for admin username and password but didn't recognise. When I go into System Preferences, and click lock to make changes, it doesn't accept either username/password. I have tried rebooting with Terminal and resetting password, but it doesn't solve the issue. is there a solution, or does it mean rebooting and doing a reinstall? I have High Sierra, with 16gb on two memory slots 8gb each. I wish I had not changed it at all, and set a new user instead! Many thanks in advance Sarah
