So you have to give them your username and password to access your computer and there looking at data on the laptop and mentioned data accessed from the laptop, VPN’s and such, so do you have to give them a VPN password? This seam like it’s going a little far, I can access any of my information, I keep a lot in the cloud, so they can force me to allow them access because I brought a computer. What if I bring a clean machine with NO data, not even a browser history? Then whats next, I have to register my passwords at the border when I’m not even bringing a computer? Because I can get to my info from any net connected PC!

They really don't need your user accounts or passwords. Heck, I don't even need those. It's real easy these days to get at your data if they want. By you 'surrending' your accounts and passwords it gives them 'permission' to search your data.
