Check which fingers you have registered with the Touch ID fingerprint scanner, so that you know whether someone else has access to your iPhone. With this guide, you can find out which fingers you have already registered and make an inventory of whether only you have access to your iPhone.
Make an inventory of Touch ID fingers
You can register a maximum of 5 fingers with the Touch ID fingerprint scanner. By default, they get the numbering of finger 1, finger 2, finger 3 and so on. They don’t all have to be your own fingers, because you can also add the finger of your partner or another trusted person. But how do you find out which fingers have already been registered so that you know who has access to your iPhone?
Touch ID: 5 fingers
The Touch ID finger scanner can be found on the iPhone 5s and until iPhone 8 Plus. Then Apple switched to Face ID, with which you can capture two different faces. With Touch ID you have more choice because you can register five fingers with which you can unlock your device. There is, of course, an easy way to find out which fingers do and which do not work: just put your finger on the scanner and you will see if it works. But if you want to get a more accurate picture of which fingers do and do not work, you have to dive into the settings. This is the only way to get a good overview if, for example, you had captured the fingers of your partner or another person. After all, these people are not always around to take part in testing.
Which finger for Touch ID?
To see which finger you have registered with Touch ID do the following:
- Go to the Settings app.
- Tap Touch ID and access code.
- Enter the pin code of your device.
- Halfway through the screen, you see a list with already added fingerprints.
- Gently place your finger on the home button without pressing.
- The corresponding finger will now flash in the list.
- If the finger is not registered for Touch ID, nothing happens.
Tip: Give the Touch ID fingers a name so that you can identify them more easily.
Naming Touch ID fingers
The above steps are an easy way to find out which fingers you have already registered. Moreover, you can now provide the fingers with a recognizable name. This can be useful if you have registered the fingers of your partner or another person. If you get into a fight with that person, you can easily remove the scanned finger from the list so that this person no longer has access to your iPhone.
