Set a Lock screen

Different types of lock screen are available depending on the Samsung device and model. The display lock prevents unauthorised persons from using the device and thus protects data. At the same time, it is the only way to unlock the device. If the unlock password, PIN or pattern is forgotten, access to the device is denied. The following types of lock screen are available on Samsung:

  • None (device not secured)
  • Swipe (device not secured)
  • Pattern (Medium safety)
  • PIN (Medium security)
  • Password (high security)
  • Face (Medium security)
  • Fingerprint (Medium Security)

Face recognition

If we have registered a face on the Samsung device, we can use it to unlock the lock screen.

Even if a face is registered on the device, by default it is not used to unlock the lock screen. For this to work, face unlocking must first be activated.

Step 3:  Tap on  Screen lock type

Use Fingerprint to Unlock

If a lock screen is set up with a pattern, PIN, or password, the fingerprint sensor can also be used to unlock the Samsung device. Multiple fingerprints can be added.

This guide shows how to enable fingerprint unlock if a fingerprint has already been registered, but if no fingerprint has been registered yet, the machine will request one.

Android 10 (One UI 2.0)
Step 1:  Open the  Settings
Step 2:  Tap on  Lock screen
Step 3:  Tap on  Screen lock type

  3. Tap on Screen lock type
  4. Enter your Lock screen Password/PIN/Pattern
  5. Enable or disable Fingerprints
  6. If no fingerprint is registered yet, follow the instructions on the screen

Auto factory reset

In the "Secure lock settings", there is an option "Auto factory reset" to factory settings. 15 incorrect attempts to unlock the Samsung device via the display lock will automatically reset the device to factory settings and all data will be deleted.

Android 10 (One UI 2.0)
Step 1:  Open the  Settings
Step 2:  Tap on  Lock screen
Step 3:  Tap on  Secure lock settings
Step 4:  Enter your Lock screen  Password / PIN / Pattern
Step 5:  Enable or disable  Auto factory reset
  1. Open the Settings
  2. Tap on Lock screen
  3. Tap on Secure lock settings
  4. Enter your Lock screen Password/PIN/Pattern
  5. Enable or disable Auto factory reset

Auto-Lock Time

The Samsung device is automatically locked when the display is turned off. One UI from Samsung offers the possibility to set a timer that starts when the display is turned off. If the device is turned on again within the set timer, the device will be unlocked automatically. Unlocking by means of the display lock is therefore unnecessary. "Lock automatically" can be set from 5 seconds up to 30 minutes.

Note: "Lock automatically" is useless when Smart Lock is enabled.

Android 10 (One UI 2.0)
Step 1:  Open the  Settings
Step 2:  Tap on  Lock screen
Step 3:  Tap on  Secure lock settings
Step 4:  Enter your Lock screen  Password / PIN / Pattern
Step 5:  Tap on Lock  automatically
Step 6:  Choose desired  Time
  1. Open the Settings
  2. Tap on Lock screen
  3. Tap on Secure lock settings
  4. Enter your Lock screen Password/PIN/Pattern
  5. Tap on Lock automatically
  6. Choose desired Time

Lock instantly with Side key

If a Lock screen has been set up, the Samsung device is locked immediately when the on/off button is pressed. When the display is switched back on directly, the password, PIN or pattern is then requested. If the "Lock automatically" function is used, this function can be switched off to save having to unlock it again.

Note: Depending on the model, the function key is meant instead of the on/off key.

Android 10 (One UI 2.0)
Step 1:  Open the  Settings
Step 2:  Tap on  Lock screen
Step 3:  Tap on  Secure lock settings
Step 4:  Enter your Lock screen  Password / PIN / Pattern
Step 5:  Enable or disable  Lock instantly with Side key
  1. Open the Settings
  2. Tap on Lock screen
  3. Tap on Secure lock settings
  4. Enter your Lock screen Password/PIN/Pattern
  5. Enable or disable Lock instantly with Side key

Make pattern visible

By default, the pattern input is visible on the lock screen of the Samsung device, which means that other people can also "read" the pattern, but to increase the security of the pattern, the pattern or input can also be made invisible.

Android 10 (One UI 2.0)
Step 1:  Open the  Settings
Step 2:  Tap on  Lock screen
Step 3:  Tap on  Secure lock settings
Step 4:  Enter your Lock screen  Password / PIN / Pattern
Step 5:  Enable or disable  Make pattern visible
  1. Open the Settings
  2. Tap on Lock screen
  3. Tap on Secure lock settings
  4. Enter your Lock screen Password/PIN/Pattern
  5. Enable or disable Make pattern visible

Lockdown Mode

Smart Lock, Face Detection or even the fingerprint sensor pose a certain security risk, and these unlock methods can be temporarily overridden by an additional button, requiring the entry of the password, pattern or PIN.

The button is displayed on the Samsung device after activation in the power on/off menu.

Android 10 (One UI 2.0)
Step 1:  Open the  Settings
Step 2:  Tap on  Lock screen
Step 3:  Tap on  Secure lock settings

Smart Lock

Samsung devices support Android's built-in "Smart Lock" feature, which allows devices to be unlocked automatically when operations are performed. This includes, for example, wearer identification, trusted locations or trusted devices. If the Samsung device is identified as being near "home" or connected to the car you already know via Bluetooth, for example, it does not need to be unlocked. However, this also means that roommates, visitors or anyone else can access the device.

Android 10 (One UI 2.0)
Step 1:  Open the  Settings
Step 2:  Tap on  Lock screen
Step 3:  Tap on  Smart Lock
Step 4:  Enter your current  PIN / Password / Pattern
  1. Open the Settings
