Re: Digital Persona
Don't give the finger to your passwords just yet...
It really depends on what you're trying to do with the security... if it's just for logging into personal social networking sites etc., and convenience is more important, then fingerprints make sense... however, I wouldn't trust digital persona with corporate accounts.
What Digital Persona does is simply store your fingerprint information on your hard drive - often in unencrypted format, so if someone can get that information and which points need to match (e.g. through browser history), it's relatively easy to make fake matches.
I use fingerprint scans on a few websites, but for a windows login, I use a combo of password and fingerprint... and do the same for some other apps on the computer.
