How to make this: I want use USB key as username/password => when is USB key in USB slot it login you automatically. When SSID of wifi (network connection) change (I set default (allowed) name in config or something), user must write password if he want login. So somethink like this. Run computer PC show me login page with users. I select user & when is USB key with password/hash in USB, it login me. Otherwise it want password. Check SSID of network. If SSID is OK (same as name in config or is allowed) => everythink is OK & I can work. Else if SSID is BAD => it want password I want protect my data. And yes I have coded data. Is it possible to do that & how??
