New password for Endless 4.0.5?

Dear friends:
Good afternoon. This morning I updated Endless to version 4.0.5 and since then, when it came back from the boot, Endless is asking for a password. I don’t know what password is this. I’ve tried the root password and the personal user password and it does not accept. Does anyone have any idea what password is this and how can I restore it? Or if it is not normal…

Can you take a photo of the screen when it is asking for the password?

Hi Daniel.
I find out a way to fix it. I remembered an old password and it’s working now. It was the old password of the root… I really don’t understood what’s happened, but, it’s ok now.

Thank you for the help!
