Know the different uses of fingerprint on your phone and how secure it is

Mobile Fingerprint

Modern smartphones are a source of wonder for many, and for most of us, it is the mini-universe where we all spend most of our time. Not only your phone responds with the touch of your finger by sensing your fingerprint but the impression of your finger can also buy anything from groceries to a new Rolls Royce car or even transfer thousands of dollars through the banking app. This feature is not confined to the top tier phones alone but even the midrange phones of today are also equipped with a fingerprint scanner. The fingerprint scanner not only keeps your phone secured by unlocking through the touch of your finger alone but with it, you can perform many functions which are not only convenient but secured as well. Here we list few of them that can make your life a lot easier.

Lock select apps with fingerprints

In case of a device being used single-handedly, you can lock it with a single password or your fingerprint. In case more than one person are using one common device, specific apps, photo galleries, and other applications of a single individual can be locked through fingerprint and the remaining applications can be used commonly. You have an option to choose selectively which apps you want to lock and which ones you want to keep open for common use. If you wish you can also lock the utilities in the settings of your phone like app installation, WiFi/Bluetooth, or even restrict the usage of phone calls. A more amazing part of the whole story is if someone wants to intrude and break into your phone unsuccessfully, a feature named as Intruder Selfie can even take a photograph of the intruder with the front camera.

Authentication of purchases from Google Play

Google Play asks you for the password in case of downloading paid apps to ensure that it’s really you who is making the purchase. Once you open Play store and tap on the settings, you will be presented with three horizontal lines which give you the option of checking the box which says “fingerprint Authentication”. If your device has the impression of your finger stored, you can complete the transaction by just placing your finger which would match with no one else except yours.

Use your fingerprint as a camera shutter

Few of the smartphones have an inbuilt feature of tapping the fingerprint sensor and take a photograph rather than a tap on the screen. This makes it easier for taking photos as the fingerprint sensor may be easily reachable rather than accessing the screen to tap on it. This feature is available in the settings of the camera app of your phone. If it’s not available, you can always add it as an extra feature to your Android phone with Dactyl making a onetime purchase paying a nominal amount.

Use Fingerprint Gestures

Fingerprint Gestures is an app which comes free with the in-app purchases which enable stored fingerprints to initiate actions like launching an app, activating the torch, controlling the music playback, changing the ringtones, opening notifications and performing other routine functions of the phone. As some smartphones have small fingerprint sensors and others have larger ones the success with fingerprint gestures may largely depend on the particular device you are using.

Keep your passwords secure

Keeping different passwords for different accounts may be more secure but remembering these different passwords is undoubtedly a hassle. Alternatively, you can create a password vault on your phone which would act as a secured place to protect all your passwords for different accounts. Although a master password can protect this vault, you can use the impression of your finger as the master password which is less taxing, more secure, and convenient as well.

How secure is your fingerprint data?

The fingerprint data that you share with your phone is too private to the device alone and is never shared with any other apps or even Google. It works as the phone notifies the apps if the fingerprint is verified. Although the fingerprint is electronically safer to use, few cautions have to be kept in mind if you use it too often. Some argue that fingerprints may be more convenient to use and may seem to be more secure, but it is easy to copy it as you use fingerprints as you touch many things leaving the impression of your finger behind. They can be copied and used to unlock your phone. If you do not run that risk in the physical environment, fingerprint is a much secure option in the communication highway as it remains private to your phone and Google has prescribed strict guidelines for the device manufacturers on how fingerprint data should be stored.
