Apple’s Touch ID: I Want It Everywhere

As I check my iPhone from time to time during the day, I’m occasionally reminded of how efficient Touch ID is. Instead of typing a passcode, my fingerprint unlocks my phone. Granted, the passcode is only four digits, but with Touch ID, I’ve set my phone to lock immediately, instead of having the security risk of leaving a few minutes before it locks. If I lose the phone, there’s no longer a several minute window for someone to access it.

I notice Touch ID more when I use my iPad, because that device does require a passcode. I use the iPad much less, though, and it’s less of a bother. And I can’t forget my Macs; I have them set to lock and request a password when my screen saver goes on, after just a few minutes of idle time. That actually bothers me more than the iPad, since I have to type my password on a keyboard.

So I hope that Apple will expand Touch ID: first to third-party developers of iOS apps, then to the iPad and iPod touch, then, hopefully, to the Mac. It would be great with the iOS apps I use which are password- or passcode-protected: the two I use most are 1Password and Dropbox, though there are others that occasionally ask for a password. I’d like to be able to get access to my passwords on 1Password with a touch, instead of entering my (admittedly strong) password, as it’s just annoying, now that I know there’s a better way.

I also hope Apple brings Touch ID to the Mac. I can imagine a Magic Mouse and/or Magic Trackpad with a section to use with Touch ID. It would need a special sensor, the same kind that’s on the iPhone, so it most likely could not work with the entire touch surface. But looking at my Magic Trackpad, I can see that if it were in a corner, it would be usable, and not get in the way. (The same would be the case on a laptop.)

As Apple often brings out a new technology first on the iPhone, then moves it to other iOS devices, or on the MacBook Air, before bringing it to other Macs, it’s obvious that they’re planning on rolling out this technology at least to the iPad in the future. Hopefully this will coincide with an SDK for third-party apps, and perhaps availability on the Mac as well. Touch ID is one of Apple’s technologies that saves a lot of time, and makes life easier. I want it on all my devices.

Update: Shawn King, of Your Mac Life, suggested on Twitter that one might use an iPhone to unlock a Mac. There could be some sort of “remote” app on the iPhone, which would let you then unlock your Mac. This might take longer, though, because you’d need to unlock the iPhone, launch the app, then unlock the Mac. But it would mean that the Touch ID would be able to interface with other hardware.
