Modern smartphones store huge amounts of confidential information, from personal correspondence to banking applications, therefore device protection is a priority for every owner. The company Samsung provides users with flexible tools for setting up security, allowing them to choose between a pattern key, a digital code or a complex password. Regularly changing the access code is an effective precaution that minimizes the risks of unauthorized entry in the event of a data leak or snooping from the outside.
The procedure for changing the security code on shell-controlled devices One UI is intuitive, but has its own nuances depending on the model and operating system version. In this article, we will analyze in detail the algorithm of actions for changing a password, consider options for restoring access if it is lost, and analyze the differences between types of screen locks. You will learn how to correctly configure biometrics in conjunction with the main password for maximum ease of use.
Choosing the optimal type of screen lock
Before you start changing the code, you need to decide which security method will be the most convenient and reliable for your tasks. The system Android on smartphones Samsung offers several options: from a simple swipe to a complex combination of symbols. The choice depends on how critical the data on your device is and how often you access your phone during the day.
The most popular method remains PIN code, consisting of at least 4 digits. This is a trade-off between unlock speed and basic security. However, to store financial information, experts recommend using Password, which can include letters, numbers and special characters. A pattern key is also in demand, but studies show that fingerprints on the screen can make it easier for attackers to select a pattern.
It is worth considering that complex passwords require more time to enter, but provide the highest level of cryptographic strength. Simple combinations like “1234” or “0000” are easily found by brute force in a matter of seconds. If you use the Smart Lockfunction, the password strength can be reduced for trusted locations, but the main lock screen should still be secure.
- 🔒 PIN: quick to enter, suitable for everyday use, but vulnerable to simple dialing of numbers.
- 🎨 Pattern key: convenient remember visually, but leaves traces on the display and can be seen from the side.
- 🔑 Password: maximum data protection, difficult to select, but requires more time to enter each time.
Step-by-step guide for changing password in settings
To change the security code, you will need access to the current device security settings. Make sure you know your current password, as the system will ask you to confirm it before making any changes to your lock screen settings. The process is performed through the main settings menu, which is available on all current models Galaxy.
Open the menu Settings and scroll down the list to the section Lock screen. In some firmware versions, this item may be located inside the category Biometrics and security. By clicking on the desired section, you will see the current protection status and a button to change the lock type. The system will ask you to enter the current code to verify the owner's identity.
After confirmation, select the option Screen lock type. A list of available methods will appear in front of you. Select the desired option, for example Password, and follow the on-screen prompts to enter a new combination. You will need to enter the new code twice to ensure there are no typos. If you switch from a pattern key to a digital password, the old pattern data will be deleted.
☑️ Password change algorithm
Please note that after changing the lock type, some biometric settings may be reset if they were strictly tied to the old authentication method. In most modern updates One UI fingerprints and facial data are saved, but for the first login after a reboot you will still need to enter a new digital password or PIN code.
⚠️ Attention: When you change the lock type from a pattern to a PIN code or password, the old pattern is permanently deleted. Make sure you remember the new combination before exiting the settings menu.
Using biometrics as a supplement to a password
Entering a complex password does not mean that you will have to enter it every time you turn on the screen. Smartphones Samsung allow you to use biometric data as a quick way to unlock, while master password remains a backup access method. This creates a balance between high security and user comfort.
To set up a fingerprint scanner or facial recognition, go to section Biometrics and security. The system will offer to add new data, guided by a step-by-step setup wizard. It is important to register fingerprints from different angles to improve the accuracy of the sensor, especially if you use an ultrasonic scanner in series models. S.
Biometrics works only after successfully entering the password when loading the device. This is an architectural feature Android: the cryptographic keys that decrypt user data are released only after entering a secret combination of characters. Therefore, after a complete reboot of the phone, you will not be able to unlock it with a fingerprint - you will need to enter it manually.
To increase the accuracy of facial recognition in poor lighting conditions, enable the "Improved visibility" option in the biometrics settings if your model supports IR illumination.
Regularly update your biometric data, especially if your hairstyle has changed, glasses have appeared or your fingers have been injured. The system Samsung allows you to store several prints of different fingers, which is convenient for unlocking the phone with both the right and left hands. Do not forget that biometrics cannot be used to confirm payments in some banking applications without first entering a password.
Actions for a forgotten password and resetting access
The situation when a user forgets the password for their device is one of the most stressful. Unfortunately, the security policy Android does not provide an easy way to restore access without losing data if measures have not been taken in advance. The only standard method of logging in without knowing the code is to use an account Samsung or Google, but this function only works with preliminary setup.
If the service has been activated on the device Find My Mobile and you have logged into your account Samsung, you can remotely unlock your phone via the web interface. To do this, go to the official website of the service from another device, log in and select the unlock option. This will remove the current PIN code, password or pattern, keeping all your files and applications intact.
If there is no linked account or the Internet is disabled on a locked phone, the only solution is a full factory reset (Hard Reset). This procedure will delete all user data, including photos, contacts and installed applications, returning the phone to its out-of-the-box state. This is done through the Recovery menu, which is called up by a combination of physical buttons.
| Recovery method | Data safety | Necessary conditions | Complexity |
|---|---|---|---|
| Find My Mobile | Full | Samsung account, internet | Low |
| Google Find My Device | No (erasing) | Google account, internet | Medium |
| Hard Reset (Recovery) | No (erasing) | Physical access to buttons | High |
| Service center | No (erasing) | Documents about purchase | High |
How to enter Recovery mode on new Samsung?
On modern models without a Home button, you need to connect the phone with a cable to a computer that is turned on. Then hold down the Volume Up and Power buttons at the same time. Hold them until the Samsung logo appears, then release.
⚠️ Attention: After resetting via Recovery, FRP (Factory Reset Protection) protection will work on devices with Android 5.0 and higher. You will definitely need to enter the login and password for the Google account that was synchronized with the phone before the reset.
Features of changing the password on different versions of One UI
Shell interface One UI periodically is being updated and the location of some menu items may change slightly. On older versions, such as One UI 2.0 or 3.0, security settings were often placed in a separate large section of the main menu. In more recent versions, starting with One UI 5 and 6, there is a tendency to group settings by functionality.
Users of the flagship models of the series Galaxy S and Note have access to advanced security settings, including folder protection Secure Folder. The password for this sandbox can be different from the main screen unlock password, providing an additional layer of protection for sensitive files. Changing the code for Secure Folder is done in its own settings, and not in the general parameters of the phone.
On budget models of the series Galaxy A or M the interface may be simplified, but the basic algorithm for changing the password remains identical. The only difference may be the speed of the menu or the presence of some advanced biometric functions that are not available due to hardware limitations of the sensors.
The location of the menu may vary depending on the firmware version, but the logical chain Settings → Lock screen → Lock type remains the same on all Samsung devices.
If you cannot find the item you need, use built-in search in settings. Tap the magnifying glass icon at the top of the Settings screen and search for "lock" or "password." The system will instantly highlight the desired section, which is especially convenient when navigating deep menus of new software versions.
Recommendations for creating a strong password
The reliability of protecting your device directly depends on the complexity of the combination you come up with. Avoid using obvious sequences such as dates of birth, phone numbers or repeated numbers. Attackers often start selecting these popular options, using dictionaries of common passwords.
The ideal password for a smartphone should contain at least 8 characters, including upper and lowercase letters, numbers and special characters. However, given the need for frequent input, you can use the method of mnemonic phrases: take the first word from your favorite song and replace some letters with numbers or symbols. This will make the password difficult to crack, but easy to remember.
Changing your password regularly, for example, once every 3-6 months, significantly reduces the risk of data compromise. If you suspect that someone may have snooped on your input code, change it immediately. It is also not recommended to write down the password on pieces of paper that are stored next to the phone, or save it in unencrypted notes on the device itself.
- 🚫 Avoid sequences like
123456,0000or2580(vertical line on the keyboard). - 🧠 Use associations and phrases that only you understand to generate complex combinations.
- 🔄 Change your password immediately if there is the slightest suspicion of a leak or snooping.
⚠️ Attention: Interfaces and menu item names may vary slightly depending on the specific phone model and regional firmware version. If you do not find the described item, check for software updates or use the settings search.
Frequently asked questions (FAQ)
Can I change the password without knowing the old one, without losing data?
Without knowing the old one It is impossible to change the password in the settings. The only way to save data is to use the service Find My Mobile from Samsung, if it has been previously configured and the phone is connected to the Internet. In other cases, a full reset will be required.
Why does the phone require a password after reboot, and not a fingerprint?
This is a standard Android security requirement. After a hard reset, the cryptographic data encryption keys are locked. Only manually entering a password, PIN code or pattern can unlock them and allow the use of biometrics.
How often should you change the password on your smartphone?
It is recommended to change the password every 3-6 months or immediately after you have entered it in the presence of strangers. Frequent changes complicate the task for potential attackers trying to gain access.
Does changing the password affect the operation of bank applications?
Changing the screen unlock password does not directly affect logins in banking applications. However, some banks may require you to re-pair the device or enter additional security data the first time you start after changing system security settings.
What should I do if the touch screen does not work and I cannot enter the password?
If the screen does not respond to touches, you will not be able to enter the password. In this case, you can try connecting a USB keyboard via an OTG adapter to enter the code and backup data before repairing the screen.
