I too would like to know how to use a local account. I am using Mac Ventura. My premium account expired a few weeks ago and I am desperately trying to decrypt all of my files on Google Drive, but the process is EXTREMELY slow, with downloads failing and needing many retries. So I want to download all my files using Google Drive and decrypt them locally
I've exported my keys but now what? When I double-click on the keyhole it says I and currently logged in and must log out. When I log out I obviously need to log in again, but that just logs me into my regular online account. I cannot create a local account (if indeed I need to do that) so now what?
