I want to load my Dropbox account on my wife's laptop, but only make certain folders available. (I have a pro account with 1TB of space, and she only has a free account with 4 GB, which is why I want to load my account on her laptop. The files I want to share with her are many GB larger than what her free account supports.) It's easy for me to set up my account on her laptop; I just need connect her laptop (running Windows 8.1) to my Dropbox account and then select the specific folders I want in the Dropbox preferences.
The problem is the security with this. I don't trust that my wife uses her laptop sufficiently securely. There's no big deal if someone unauthorized gets access to the particular folders that I want to enable on my wife's laptop. However, I am concerned that if someone physically accesses her computer, they might then go into the Dropbox settings and then enable any of my other folders, most of which I doon't want anyone to access.
Thus, I'm looking for a way to password-protect Dropbox settings so that even if someone has physical access to her laptop, they would need a password to change any of the settings. I can't find if Dropbox has a built-in password for this. If not, is there any other solution I could use for this?
I'm aware of the possibility of password-protecting a Dropbox crypt, such as suggested here: Is there a way I can password protect a dropbox directory on my work pc?. However, I'm not ready to go that far just yet. All I want is to password-protect the Dropbox settings on a local computer.
