Why is there no solution for the "my password isn't working after installing OCLP"? This happens a lot and I have yet to see a solution.

This is a known problem and I have not seen any official solutions or any comments that people recommend to fix this. Why would a password that is correct suddenly stop working?

I had this happen the other day to an OCLP Mac that I booted in Safe Mode. It had automatic login enabled so I don't know if it would have failed at the lock screen, but when I tried installing an app it would not accept my password (but would accept my password to "change" it in System Settings).

I've seen this happen across different macOS versions so it's not an OS-specific issue.
