IMac Help Needed

[Ken Dryden]

My iMac computer is repeatedly failing to accept my password. It also offers the option of a recovery key, though I don’t remember setting one up.

Any tips to resolve this issue? The website is of no help.

Do you mean you type a password and it says wrong password or wrong password/id combination?  Do you have more than one user account on the machine?

I accidentally set up two user accounts when I bought it but never use the other one. Not sure I could find that password now.

Try to verify that you are logging in to the correct account for the password.

I am. I was able to change the password in January when this happened previously, but no luck today.

Well, if you made sure caps lock is off and tried your regular password on both ids you're kind of stuck.  Mac has this "Start up from macOS Recovery" process you could look up.  Or you can reboot and try the reset  options in the login window.  That's about as far as my expertise goes - there are probably some mac folks here who can help.

Do you have everything backed up? Apple should be able to walk you through a password reset via the phone.

Finally solved, I found an Apple program that was interfering with accepting the password and I disabled it.

Which program would do that? If it could possibly block your access, I'd remove it, never mind disable it.
