Apps pin has locked me out of valuable info I need on a daily basis.

I attempted to add the feature of having a pin for your valuable apps. When I got to the password enter, I thought I was choosing a password. I don’t remember using that feature in the past. I put what I wanted and it came back invalid password. So I tried and went in circles trying to get help but I also can’t remember my account password. I need help. I sent support a message for help and after it sent on the bottom it said we’ll be with you shortly via email. Well, they can’t reach me that way because that is one of the locked apps. I sent them an alternative email they can reach me at. No answer yet. I am frantic because I need to use the info I have stored on those apps every day. All I want to do is find out how to get back to the feature and switch the blasted thing off! Help!
