Boot into Recovery Mode and choose Terminal. At the prompt enter "resetpassword"( no quotes). The reset password screen will appear. Select your startup volume, then from the pop-up menu below select a user account. Enter and confirm your new password. Click Save and choose Restart from the Apple menu. Your Mac should now use the new password.
Is this happening after the reset password was done and were you able to login? I don't know what that's about and if you can't open iCloud preferences or dismiss it, I'm not sure how to proceed.
Perhaps the best course of action would be to restore from your TM backup.
You wrote - Remind me never to do that , you can delete the login keychain and create a new one from keychain access or from recovery mode but most imp is iCloud verification code , if the user don't remember the iCloud verification code that can be newly created by creating a passcode in an iOS device than setting up the keychain , just a mere practice will do .
I have restarted the Mac but I can see a pop up can't connect to iCloud because a problem with your mail address , open iCloud preferences for problem , how to further proceed .
I am not using time machine on this Mac , 😟 .
No worries , still seeking for help .
Whew! So you are all good now? Remind me never to do that. I will write my Admin password on my eyelids!
forgotten admin password
