This is a great question and I look forward to reading some informed responses.
When I'm on the road, I have my passwords in a KeePass database that I carry on my person. No login passwords on the laptop* itself. And that particular database is just a subset of my passwords, and it excludes all my banking and investment company logins, as I'm just not on those daily and so there's no need to have them in my travel password database.
I much prefer to be wired in by ethernet cable, but that's getting increasingly hard to find. It's wifi everywhere.
* the laptop happens to be a Dell with Linux pre-installed - acquired in the brief window of time they sold inexpensive ones (now they just have one, developer-level Linux laptop) - and that requires a password to boot as well.
