1. Set a pattern password to lock the phone
As the camera functions of smartphones continue to evolve, many friends have saved a lot of private photos on their phones. Coupled with many private emails or other contact information, the issue of privacy protection on mobile phones has become increasingly prominent. Therefore, it is still necessary to lock your smartphone, which can be easily accomplished by using the Android system's swipe-type touch screen pattern password protection.
First enter the setting interface and select "Security" → "Set Unlock Pattern". After entering the personal identification pattern password here, open the security settings interface again and select the "Use visible pattern" option. In this way, you can lock your phone with a pattern password.
2. Password to protect Android phone
Saving username and password information on web pages browsed on an Android phone is obviously a brainless and stupid approach, and it also means that some people with ulterior motives will be able to easily invade your Email or obtain one of your forum accounts or even It's bank card information. To protect these stored passwords (called credentials) just in case, you can use the following methods to maximize the security of your saved credentials.
Enter the setting interface and select "Location & Security" → "Credential Storage" → "Set Password".
3. Lock phone SIM card
We cannot prevent 100% of the phone from being lost, but at least we can prevent it from being used by some people with bad intentions if it is lost. The method is to lock the SIM card.
Enter the settings interface, select "Location & Security" → "Set Up SIM Card Lock", and then enter the PIN code obtained when purchasing the SIM card. After doing this, others will not be able to use your phone to make calls or send text messages without entering the PIN code.
The settings of the three major firewalls start with setting the lock screen password of the mobile phone, then the password of the mobile phone to prevent the important information in the mobile phone from being leaked. Finally, the password setting of the SIM card of the mobile phone can prevent others from using it after the mobile phone is lost. You can't make calls or send text messages from your phone without entering your PIN.
