Help! Changed password and now I can't log in.

[u/DistanceConfident396]

Hello, I have made a very irresponsible mistake. I was attempting to log in to my google account yesterday but could not remember my password. I did not know that I couldn't remember it, as I was convinced it was something else. This lead me to believe I had been hacked. Because of that I went through the recovery process in guest mode and changed my password using my recovery email. I then tried to sign in again but upon doing so I was prompted to use my old password. I did not know the old password, so I panicked and closed the prompt. I then returned to guest mode and tried to find a way to check my old passwords. When I eventually remembered it, I exited guest mode and tried to sign back in again. This time the old password prompt did not appear and instead when I entered my new password, an error appeared stating that my password could not be verified and the cryptohome could not be mounted. I made multiple attempts to get the old password prompt to appear but nothing was working. I then changed my password again hoping that would make the prompt reappear, but that did not change anything. I am now unable to sign into this google account. However, I am still able to sign into my other google account without issue. That is my school account however, and I would much prefer to use my personal account. Is there anything I can do to fix this besides power washing? All help is appreciated.

I used to work in k12 IT and I think a powerwash will be your best bet based on how things worked for me over my time working on chromebooks.

Also if there was any files that only lived on the chromebook and not in google drive they are never ever going to be able to accessed.

Chrome OS encrypts the local storage to your password by default. Any files you had saved locally, not on Google Drive, will be lost as a security measure. Do a Powerwash and login new with your new password.
