Unlocking your smartphone is an integral part of our everyday lives these days. On average, we unlock our smartphones up to 80 times.

We will introduce you to the different unlocking methods, from passwords to facial recognition software, with their respective advantages and disadvantages, in this magazine article.

Face Unlock

Face unlocking is one of the most modern and convenient ways to unlock your smartphone. With this method, your face is scanned, and the smartphone recognizes the owner based on facial features. This method is very safe because it only works when the smartphone recognizes your face. However, there are also disadvantages: if you wear sunglasses or your face is covered by a hat or scarf, face unlocking may not work. There are also security concerns, as it is possible to fool the system with a photo of the face. Nevertheless, facial unlocking is an efficient method to unlock your smartphone quickly and easily.


  • Unlock quickly and easily; all you have to do is hold your face in front of the camera
  • Difficult to outsmart with 2D or 3D cameras
  • No password is required, saving time and effort


  • can be tricked by photos
  • Faces are not consistently recognized in low light
  • not available on all devices
  • Sharing biometric data can pose a security risk

Iris Scan

With the iris scan, you get another modern method to unlock your smartphone. This involves scanning your eye and using it as a biometric characteristic. Due to the uniqueness of the iris, this method is very safe. The iris scan cannot be fooled by photos or videos of the eye. However, it can sometimes be challenging to position the eye correctly, which can cause the scan to fail. It can also be uncomfortable to keep your eye open for long periods. Nevertheless, the iris scan is a promising method to securely unlock your smartphone.


  • secure unlocking thanks to the uniqueness of the iris
  • convenient because no input is required
  • Possibility for physically disabled people to quickly unlock their smartphone
  • hygienic method, as there is no contact with the smartphone


  • not always unlockable in dim light
  • Glasses and contact lenses can cause difficulties


The fingerprint method is now prevalent and is offered by many manufacturers. The fingerprint is stored on the device and can then be used to unlock it. A unique feature of this method is that it is very safe. Because every fingerprint is unique and cannot simply be copied. It is also very convenient as you can easily unlock your device with the touch of a finger without having to enter a password. However, you should make sure that you only save the fingerprint on a secure device and do not pass it on to third parties.


  • Fingerprints are unique to each person; therefore, high security
  • quickly and conveniently
  • multiple fingerprints are possible for unlocking (e.g. for family members)


  • Fingerprint copies can be made with great effort
  • wet or sweaty fingers and a dirty display can cause difficulties
  • The fingerprint sensor may be faulty or allow incorrect fingerprint

The password is one of the classic unlocking methods. But what makes a good password? It should be at least eight characters long, contain uppercase and lowercase letters, numbers and special characters, and should not be easy to guess. Avoid birth dates, names of pets or family members, and simple words like “password” or “123456.” If you have a strong password, this method is very secure. However, there are also disadvantages to using a password, even if it is secure. On the one hand, it can be not very pleasant to have to enter the password every time. On the other hand, there is a risk that someone will look over your shoulder and spy on the password.


  • secure protection with a secure password
  • Password can be created in any length and any language
  • not device-dependent
  • easy password recovery


  • easier to outwit with weak passwords
  • complex passwords difficult to remember
  • no convenient and quick unlocking method


The good old PIN is still a popular method for unlocking your smartphone. You enter a four to six-digit number combination to gain access to your device. But be careful: a PIN that is too simple, like “1234”, can quickly be cracked. It’s better to choose a slightly more complex combination to protect your smartphone. The advantage of the PIN is that it is quick and easy to enter.


  • Input is easy and quick
  • device independent


  • can be guessed more easily
  • consists only of numbers
