I was having a problem with a pointer so after installing latest system updates with no effect on crazy pointer, I did a PRAM reset.
From then on, a log in page has changed:
- my user name has changed (in past i was using my whole name as login name. Some months ago, I changed it for a 'nickname'. But now, after PRAM reset, the old/previous user account name appears.
- there was another account 'guest' not secured by password. Now the password is required.
- 'my account' with changed user name doesn't accept my valid password. When typing a password incorrectly for 3 times, there is pop-up to log in with my apple ID. That does not work either. The password is correct.
I am using this:
- MacBook Pro 2011 late
- latest operating system with updates
- I never changed my apple ID since created
- changed my Apple ID last year
- changed my computer password also about a year ago

It seems like the main issue to address here is being able to log in again with a valid password. Once you've done that the rest can be sorted.
Since you've got a late 2011 MacBook Pro, you should be able to use these steps to reset your password from Recovery Mode:
resetpassword
(all one word, lowercase letters)Let me know if this doesn't work.
