One of the most common questions that have come up with this new element, is how we can identify and remember which fingers have stored on the iPhone or rather, their tracks. All we have to do is go to Settings> General> Touch ID. Once inside, you will find a list with the number of smell that we have saved. But the problem comes when we want to know exactly what traces correspond to each finger and have not properly identified. To do this, we only put our finger on the reader as usual, and if that finger footprint corresponds to one of the already stored, it will emit a flash of gray.
To have identified that fingers have saved, it is best to click on "edit" (in the upper right corner) and rename the different tracks according to the corresponding finger.
And you, do you use the Touch ID in your everyday life or, conversely, prefer the four-digit code?
