Get Touchy

Touch ID by Apple is one of its kind revolutionary finger print reading technology that is brand new and never introduced by any other mobile manufacturer in the past. It was first released in iPhone 5S and is now getting an upgrade in Apple’s latest operating system for both the mobile and desktop environments. It enhances personal security by replacing the passcode based login system with a fingerprint sensor.

It also helps users authorize payments on Apple Pay and would now support third-party application access in its upgraded OS. It has not only improved security by reading each fingerprint but has also increased the convenience of authentication during login and purchases. Now you can just press your finger on the sensor instead of typing in long and obscure passwords every time you log into your device or buy anything.

Since its announcement, the technology has been a topic of great speculation from experts regarding its effectiveness and level of security it would provide. Surprisingly, Apple developers have designed the system into one of the most secure authentication processes in the industry.

They have secured the sensor with a highly scratch resistant sapphire while the sensor is easily able to read each finger touch – the moment the user places their finger on the home button. The sensor detects a high-resolution snapshot of your fingerprint that is verified with the stored signature hash. If the fingerprint matches, you are logged in, else the attempt is rejected by asking the user to enter the passcode or try again.

Unlike usual fingerprint sensors, the Apple sensor does not just scan your upper skin. It also scans the sub dermal skin so that the most accurate fingerprint can be used for authentication. The whole verification process happens in a fraction of a second, making it even more usable by its customers. Surprisingly, the scanner can detect any of the five fingers for authentication, which allows added levels of security. The process is repeated every time you try to make an app purchase or pay through Apple Pay.

Effective use of Touch ID enhances your iPhone experience while increasing your security and privacy. The underlying software is intuitive, which means the more you use Touch ID, the better it becomes at correctly recognizing your fingerprint.

Following is a list of Why-To’s that demonstrate basic Touch ID usage and help you get started, if you already haven’t.

At first you need to set up touch ID by adding your fingerprints since during this process, the App creates a keychain that stores a unique ID for your identity, which helps in future verification.

The app may sometimes fail to identify your fingerprint when you are using it for the first time, but as it is a self-learning application, the more you use it, the better it would become at recognizing your identity. So use it as much as you can and you’ll find it greatly improving your experience.

Touch ID has up to 5 slots for storing your fingerprints. You can also store the fingerprints of your colleagues or family members. This is more secure than providing your pass code as your passcode can be gained by anyone but the fingerprint sensor will only allow verified individuals. This is especially useful if you share your device with others at work or home.

Renaming and labelling your fingerprints allows for proper classification and access to each persons identity. The default labels assigned to stored fingerprints makes it difficult to find the right person’s identity. Thus renaming it will allow you to keep track of all persons registered to use your device.

Remove Fingerprints from your iPhone Touch ID

Touch ID allows you to share your device without actually giving away your passcode. But sometimes you may also have to remove access provided to some individuals. Sometimes, your fingerprint may become glitch and you may have to register it again.

Therefore you can remove your fingerprints as easily you can add them from the same console provided by the Touch ID app.

Turn Off Touch ID for Lock Screen and App Purchases

Some users prefer the passcode based authentication system more usable than Touch ID. Apple allows you to easily turn off your Touch ID based login procedure so that you can revert to the passcode based system. The app also allows you to turn off Touch ID for app purchases and Apple Pay. So you can use any authentication system based on your preference.

Touch ID Apps to Consider

Recent iOS and Mac upgrades have allowed Touch ID API access to developers, opening a world of new possibilities for users. The app store is now flooded with apps that use Touch ID for a variety of custom authentication procedures that lack in iOS. Now you can easily authenticate your apps using Authy or unlock your computer using Fingerkey.

You can also maintain privacy of your Google Voice records using GV Connect and maintain a private journal using DayOne. The possibilities are limitless and as the upgraded OS becomes mainstream, we are likely going to see a great rise in Touch ID enabled apps.

Final Thoughts

With a major part of our lives getting online and much of it moving from our computers to our iPhones and iPads, protecting data and privacy has become paramount. Apple’s Touch ID is a step in the right direction to offer its users with a unique solution. As more developers exploit its utilities, our smartphones will continue to muscle their way into our lives.

It’s all set to replace the humble wallet with the advent of Apple Pay using Touch ID. Biometric authentication brings in an element of security to the mobile innovation.
