10 Top iOS Apps Secured by Touch ID

Introduced with the iPhone 5s and refined in the iPhone 6, Touch ID is a marvel of simplicity and security. Press the home button to turn your phone on, and use your thumb or finger to log in with your fingerprint. What could be easier? But once you upgrade to iOS 8, you can do more with Touch ID than just unlock the phone.

Use Touch ID CorrectlyHave you fully taken advantage of Touch ID for basic security? Once you've enrolled several fingers, you need to set up a strong passcode. That four-digit PIN Simple Passcode is no good. It was never good, but nobody wants to enter a strong passcode every time the phone needs unlocking.

In Settings, turn off Simple Passcode (Setting > Touch ID & Passcode > Simple Passcode) and enter a new, strong passcode. You only have to enter it when you want to change Touch ID or passcode settings, or when you power your phone all the way off and on again. Now on to the apps!

Cloud Storage AppsStoring and sharing important information in the cloud is incredibly convenient because you can get at your photos and documents from any device. But to make sure the wrong people don't access your cloud storage, several vendors have added support for Touch ID.

Box is one of the more established file-syncing services on the market. The Box iPhone app gives you access to all those files you host in your Box account from practically anywhere, and Touch ID support keeps your files secure.

File-syncing fiends might find other services with extra options, but Dropbox keeps its experience simple and straightforward, making it one of the best free iPhone apps you'll find. Dropbox just added Touch ID support this week, which may have been a reaction to the news earlier this month that Microsoft OneDrive added Touch ID support to its iPhone app.

Password Managers Everyone knows that you must use a super-strong master password to protect the data stored by your password manager. However, typing something like 'TBonTB489&#' on an iPhone keyboard is awfully difficult. How much nicer to log in using Touch ID!

1Password stores more personal data than most password managers, but only some of that data is available for form filling. Now you can access your passwords and personal data on the iPhone via Touch ID.

With revamped secure sharing and a new emergency contacts feature that passes on your data if something happens to you, Dashlane is better than ever. Touch ID support is icing on the cake.

Mobile support in Lastpass isn't free, but a buck a month for the premium edition is quite a deal. Now Touch ID puts all of LastPass's considerable password-managing power at the tip of your finger.

Other Apps Search the iTunes store for 'Touch ID' and you'll come up with dozens of apps for a variety of purposes. Here are a few of the more notable apps that truly benefit from Touch ID.

With the Amazon app, you can find and purchase just about anything from your iPhone, and Touch ID ensures that nobody else can make purchases on your account.

Your eHarmony app profile probably contains some seriously personal details, things you wouldn't want the kids to stumble on when you let them play Angry Birds on the phone. Touch ID ensures they can't venture into your romantic life.

When it comes to staying organized by keeping track of ideas and other information, Evernote for iPhone does the heavy lifting for you. Protecting your ideas with Touch ID ensures that nobody can snoop those ideas.

The Mint app puts your financial life in your hands, providing real-time information about all your account transactions and balances. Activate its Touch ID support to make sure you're the only one getting that real-time information.
