The TouchID feature has been available since 2014 with the first release of the iPhone 6. The feature allows you to instantly sign into your phone by holding your finger on the home button. Users will find the feature is easy to use and highly secure.
Users are able to program more than one fingerprint on their devices that allow you to unlock the phone with different fingers for different grips or to allow other trusted users to unlock your phone. The feature basically automatically puts in your password, but should you need to open with a code, you can just swipe to the left as usual.
Many users are unaware that the feature can be used with individual apps as well. The feature allows you to program your iTunes password this way, meaning you do not have to enter your password each time you download an app. Simply hold your finger on the home button and it will enter the password for you.
Many of us prefer passwords on certain apps such as email, cloud accounts, chats, and much more. However, these passwords are not always safe as others might see you enter the code without you knowing, which is why the TouchID is so useful. The feature unlocks the app within a second and others will never know what the actual password is.
DropBox
DropBox is one of the most popular online storage apps that can be accessed by your mobile device or PC. This allows you to store contacts, media files, and just about anything else and still have access to it even if your device goes missing or has been replaced. The app also works well with the TouchID feature, which will automatically input the password created for your account.
PayPal
PayPal is an online banking service that allows you to purchases various items and services online, meaning it needs to be secure and kept safe. The TouchID works brilliantly with this app as well, which once again enters your password for you when the home button is touched. Users will still be able to enter the password manually, but as an added security feature, the TouchID provides your password in a hidden manner no matter where you are.
