I need to fix the encrypted login screen
I am starting at a job and have never encountered a login screen like this. I figured out what it is for, It comes up anytime there is a password required. I would like to remove the encryption. Unsure of how to remove that feature? I have tried the security under preferences - feels like a third party app. Unsure. Any help in cleaning this up would be great.
