For work I VPN in and then use a virtual Windows desktop. Work is very security-conscious, so I decided "likewise!" and made a login I only use for work. Needless to say it does not have su permissions . I didn't bother making any mods to this one. It only has the bare minimum in a launcher, things I might need in a hurry in case I can't log in and have to call support, for instance. The Chrome launcher goes straight to the VPN login page.
