Being required to sign in on my pc every day on every app/website

Every day I am kicked out of my apps and the websites where I have a registered account. I have to log in again every day, even when I’ve checked the box to stay logged in. My laptop often closes down on its own overnight, so all of my tabs are gone the next day. Then Google asks me (again) for my 2-step verification on my phone, even though I’ve checked the box ‘not to ask on this device again’. I know it’s got to be something in my settings, but I don’t know what to do.
