Keychain Password

Login keychain password is same as the the admin password and always remembered by an administrator , it can't be viewed in keychain access , however can only be reset if one forgets it https://support.apple.com/en-in/HT202860

Have you set up iCloud Keychain , what are the versions of Mac , what does it mean admin password is not working can't you sign in and locked the account .

if keychain access is opened through spotlight , and press command and comma to open keychain preferences , a pop up window appears , if reset my default keychain is clicked .

login keychain is deactivated as well as iCloud keychain , you have to again fill up the passwords using https://support.apple.com/en-in/guide/safari/ibrwa005/13.0/mac/10.15

in user library , in keychain primary folder a new key chain sub folder is created and the old sub keychain folder is deactivated ( you should never delete the old keychain sub folder from the user library ) .

The old passwords stored in keychain that you inquired will be definitely deleted , say if you had back up the Mac with time machine and you think by absorbing passwords from time machine back up and substituting them in user library > keychain folder is impossible , and passwords are encrypted you can't read them .

I've tried my admin password and it is not working. This has happened on both my macbook pro (now) and my iMac (last week). Im not able to access things I would normally, I don't remember ever having this issue in the past.

both my 2018 MacBook Pro and my 2016 iMac are running 10.15.1, I know my admin password. When I got this box to enter login keychain password, I entered my admin password as it's the only one I've ever used. Didn't work. Apple Chat had me create a new keychain, and great now I have access to one thing, but the hundreds I had saved on the other keychain are gone.
