I understand that this increases the security risk, however, I willing to take tradeoff for the convenience.
While using my laptop I have multiple things I need to login to. A few of them are:
- Initial Windows XP login
- Login after I lock it (Win + L) or screensaver
- Firefox
- Thunderbird
- RoboForm
Here is my dream scenario. (My current laptop doesn't have bluetooth, so I would use a USB adapter for this.)
I wear my cellphone on my belt. The laptop senses my cellphone and prompts me for a password. As long as it keeps the connection with my cellphone the screensaver doesn't kick in. When the connection is broke, for example when I go to fill up my coffee cup, the screensaver kicks in and locks the computer. When I return it prompts for a password.
Every application that requires a password is automatically detected by the application and answered so I never need to enter in a password other than the master password.
There would be the usual override with a more complex password that would allow me to unlock the computer if I do not have my cellphone with me.
This is definitely possible today from the technology standpoint, but has a vendor refined a product well enough to actually do this and do it well?
