I mean this is what I use 1password for.

If it's the IT managed computer login then you couldn't use a password manager for it, right?

I think this is more the realm of using windows hello or apple touchid (AFAIK no good, simple, standard built-in way exists for linux distros) to get the first OS login and then you can use your password manager when you are logged into the OS.

I tend to never use my password manager for my primary OS logins for desktops/laptops I physically access. Fortunately, I rarely have to keep more than 5 or so memorized at a time (including my password manager, Bitwarden/Vaultwarden).
