DropBox is cool. I use it to keep my many computers in sync. This includes keeping my password manager master safe file in sync (you all use password managers, right?) Even though that file is encrypted with a good encryption algorithm, it’s still a file I would like to protect. I used a pretty strong password on my DropBox account, but it’s still just a password.
Fortunately, though, DropBox now supports two-factor authentication. If you have a Google account, and you use Google’s two-factor authentication (like you should!), it’s incredibly easy to add, because it works with Google Authenticator. Just enable two-factor in DropBox, go to Google Authenticator on your phone, add new account, scan the barcode, and done.
Hopefully, this means that two-factor authentication is becoming more mainstream. I’ll be a lot happier when Facebook supports it, but for now, DropBox support is fantastic.
