Secure your smartphone with OPPO fingerprint lock

2019-02-19

If someone uses your smartphone without your knowledge, or your phone is lost or stolen, you need to be confident that your personal data and accounts are secure. OPPO phones use multi-factor authentication to make sure only you can unlock your device.

 

Depending on the model of OPPO smartphone you have, you may be able to unlock your phone, secure apps and perform other functions using your unique fingerprint. You can add up to 5 different fingerprints on your OPPO phone, which can't be easily hacked like a passcode can.

 


How do fingerprint scanners on phones work?

 

Fingerprint scanners are now a common feature on phones across all price ranges. By storing your unique fingerprint in your phone, you can lock or unlock the device, secure apps and files or even make purchases simply by touching the screen when asked. But how do fingerprint scanners work?

 

There are three major types of fingerprint scanning technology, which offer different levels of security.

 

1. Optical scanners – rarely used today, these scanners take an image of the fingerprint and analyse this image to determine whether it's a match for the saved fingerprint. However, as optical scanners only scan a 2D image, they can sometimes be fooled by false fingerprints or photos. The hardware required is also too bulky to suit today's modern slimline smartphones.

 

2. Capacitive scanners – the most common type of fingerprint scanner on smartphones, capacitive scanners use conductive plates that detect the ridges and valleys of fingerprints pressed against them. These scanners are much harder to fool than optical scanners, especially at higher resolutions, but they may still be prone to hacking.

 

3. Ultrasonic sensors – a new type of fingerprint scanning technology used in high-end smartphones such as the OPPO R17 Pro, the scanner sends out an ultrasonic pulse that is absorbed or bounced back by the ridges, valleys and pores of the fingerprint. This creates a detailed 3D image of the scanned fingerprint that is very difficult to fool.

 

Is fingerprint more secure than password?

 

Unlike passwords that may be guessed or hacked, a fingerprint is unique to the individual. Someone looking over your shoulder may see you enter your passcode or phone pattern code and remember it, but they won't be able to use your fingerprint.

 

Even if someone doesn't know your password, the chance of guessing or cracking a four-digit passcode is 1 in 10,000, while the probability of a fingerprint matching is 1 in 50,000. Security experts recommend using two-step authentication that combines a passcode with fingerprint or face recognition for extra security.

 

How to open your phone with fingerprint

 

It's recommended that you set a passcode and save your fingerprint or face ID when you set up your OPPO phone for the first time. You need to set a passcode first before you can add a fingerprint.

 

This guide is applicable for OPPO smartphones using ColorOS 5.0 and above. You can check what ColorOS version you're using by going to [Settings] > [About phone].

 

How do I set a passcode?

 

There are several types of passcodes to choose from on OPPO phones. Depending on the model you have, these can include:

 

·        6 Digit Numeric Code – the default passcode option, a numbers-only passcode containing 6 characters

·        Pattern Code – a phone pattern with at least 4 dots connected in a line

·        4 Digit Numeric Code – a numbers-only passcode containing 4 characters

·        4-16 Digit Numeric Code – a numbers-only passcode containing between 4 and 16 characters

·        4-16 Digit Alphanumeric Code – a passcode containing between 4 and 16 numbers and/or letters

 

A passcode is more secure than a phone pattern. The longer and more complex a passcode is, the more secure it will be. To set your passcode:

 

1. Go to [Settings] > [Fingerprint, Face & Passcode]

 

2. Tap [Turn on Passcode]

 

3. Set a 6-digit passcode or choose [Other Encryptions] to enter a different type of passcode or phone pattern

 

4. Enter your passcode or draw your phone pattern again to confirm and activate the code

 

How do I set up a fingerprint?

 

After you've set a passcode, you can add one or more fingerprints to your phone.

 

1. Go to [Settings] > [Fingerprint, Face & Passcode]

 

2. Tap [Add a Fingerprint]

 

3. Gently place your finger on the [Home] button until you're notified that the fingerprint has been recorded

 

4. You can choose to repeat the above steps to save up to 4 more fingerprints

 

Now that your fingerprint has been saved, you can set it as the default authentication to unlock your phone.

 

How do I protect apps with fingerprint?

 

As well as locking your phone, you can also use fingerprint sensors to secure apps and protect your private data. To enable app lock on OPPO phones:

 

1. Go to [Settings] > [Security] > [App Lock]

 

2. Enter a passcode and security question or choose [Other Encryptions] to use a phone pattern lock, 4-16 digit alphanumeric code or fingerprint encryption if this option is supported

 

3. Select the app or apps you want to lock. Toggle [Start Passcode Verification] until you see a padlock symbol on the app.

 

Anyone trying to use the app on your phone will now be asked to complete authentication.

 

How do I reset my fingerprint?

 

If you want to delete any fingerprints saved on your phone, or to add a name to a fingerprint, here's how do to it:

 

1. Go to [Settings] > [Fingerprint, Face & Passcode]

 

2. Select one of the fingerprints you've saved

 

3. Edit name details or tap [Delete Fingerprint]

 

After deleting a fingerprint, you should save a new fingerprint to make sure your device is still as secure as possible.

 

How do I reset my password with fingerprint?

 

If you want to reset your phone passcode or you've forgotten the passcode, you can use your fingerprint to access the device and enter a new password. At least one fingerprint must be saved to your phone already for this to work.

 

If the phone is locked

 

If you can't get past the lockscreen of your phone, here's what to do:

 

1. Enter your passcode incorrectly five times

 

2. Your phone will ask you to wait for 30 seconds before trying again

 

3. Choose the option [Use Fingerprint to Reset Passcode]

 

4. Place your finger on the screen as instructed to unlock the phone

 

5. Set and confirm your new passcode

 

If the phone is unlocked

 

If your phone is already unlocked, but you've forgotten your passcode, you can change it using your fingerprint in the [Settings] menu:

 

1. Go to [Settings] > [Fingerprint, Face & Passcode]

 

2. Enter your passcode incorrectly five times

 

3. Your phone will ask you to wait for 30 seconds before trying again

 

4. Choose the option [Tap to reset passcode]

 

5. Place your finger on the screen as instructed to unlock the phone

 

6. Set and confirm your new passcode

 

How do I change a passcode without fingerprint?

 

If you already know your passcode but you want to change it, you don't need to use your fingerprint. You can simply use your existing passcode for verification.

 

1. Go to [Settings] > [Fingerprint, Face & Passcode]

 

2. Select [Modify Passcode]

 

3. Enter your existing passcode or phone pattern

 

4. Enter the new passcode or phone pattern you want to use, choosing [Other Encryptions] to see more options

 

5. Enter the new code again to confirm it

 

It's recommended that you change your passcode periodically to help keep your phone more secure.

 

If you want to turn off the passcode, select [Turn off Passcode] from the menu and enter your code to confirm.
