The infamous Touch ID fingerprint identification framework has become a very common and useful feature. It almost seems odd and slightly archaic to type in a password to log into a service. There are murmurs going about that OS X might be getting an update that uses the ubiquitous Touch ID to interact with your Mac.

Apple Touch ID

Bluetooth would make Touch ID a valid and secure fingerprint reader for OS X

There are already several apps that already use a Bluetooth connection to wake-up and unlock your device, thus alleviating the need to actually enter your (hopefully) complex password. This rumored inclusion by Apple would leverage the Touch ID sensor itself as the means for unlocking as opposed to simply the presence of your device. This is actually quite secure and a very good idea. This means you’ll need something you own and something you are for logging in, which is far more secure than a traditional password alone and much more secure than using the Knock 2.0 or similar apps.

Touch ID could also be used in conducting financial transactions using Apple Pay online. Allegedly, once the framework for that is completely integrated into the browser, you might be able to use your fingerprint to confirm purchases on your PC using that reader. It would be interesting if they include this functionality with third-party readers, such as the capacitive reader that Synaptics is looking to integrate into more devices.

OS X already supports several different methods to increase security at login which is similar to how Windows is starting to introduce more secure options for consumers. The problem is that these options aren’t always the most well known for users of OS X. Having more options to keep your private information safe is always good, especially when using these new technologies is simple, and even somewhat natural at this point.
