Trouble logging into macOS When I left my MacBook Pro for a minute, it closed out, which is normal. But, when I returned, it refused to accept my password to my regular administrator account. So I clicked on Guest User to see if I could log in through there. Now I can’t log into Guest and there is no way I can get back to my regular login. It does not want to accept my password.

How might I troublsehoot this further?
I fixed the problem by doing the following steps in this video. Here is the link to the video on youtube: https://www.youtube.com/watch?v=TjxAgiNqkDM
