Hey Darren. Sorry this is a frustrating problem but there may be a solution for you.
I will reference what the answers say here to help: https://answers.microsoft.com/en-us/windows/for...
Press your windows key + X > Type netplwiz in the run prompt > uncheck user needs to use password for the account.
You can also go to settings - account - sign-in options > choose sign in with local account, and you will have to enter a pin ONE time > leave new password and confirmation empty > log out and back in > should be fixed and you wont have to enter anything.
If none of this works you may try to use windows key + X > netplwiz when it asks for a username and password, enter the full email address of your Microsoft account and the password > you'll never have to enter a PIN again.
Let me know if this works out for you.
I have that already so it auto logins when I switch my computer
the problem comes in when you lock it. (say there someone around and you do not want them on your pc) now when I unlock I have to go and setup a **** pin ever **** time
how do I get it to stop doing when I have just locked windows for few mins
