When we showed you how to set up and use iPhone 5s’ Touch ID fingerprint sensor, we told you that you can add only five fingerprints.

If you’ve already added 5 fingerprints to your iPhone 5s, you may have noticed that the “Add new fingerprint…” option is greyed out.

But, YouTube user Note Suwanchate has discovered a cool trick that allows you bypass iPhone 5s’ Touch ID’s five fingerprint limit.

The trick is to use multiple fingers while you’re adding a fingerprint rather than just one finger. Touch ID can’t figure out the difference, so it accepts it. After you’ve successfully added a fingerprint using multiple fingers, you’ll be able to use all the fingers to unlock the device.

Here’s the video where we demonstrates it.

In some ways, it is a lot more efficient way to add your fingerprints to device than doing it one by one.

Please note that the error rates will be higher with this method. We’re also being told that by doing this we’re registering a wide range of acceptance for each finger, which may make it less secure. I guess it may be better to wait for the iOS 7 jailbreak to remove this restriction.

Thanks Alan for the tip!
