There is a privacy feature in the iOS 6 system, which can turn on and off the corresponding permissions for the apps installed on the phone. For example, Contacts, such instant messaging software accesses our contacts, which can theoretically increase the security of mobile phone data.

Just start it in the settings.

Steps: 1. Turn on your iPhone and find the "Settings" icon to enter.

If you want to set a complex alphanumeric multi-digit password, you need to turn off the "Simple Password" switch.

5. Set the input password, and enter the four-digit number in the simple password mode.

6. Enter the password again to ensure that it is exactly the same as the password in the previous step.

7. The password will take effect immediately after the setting is completed, and you can also close the password and change the password in the setting. You can also set up programs that allow access when locked, and even more aggressively: erase data.

After the user enters the password 10 times, the system will erase the data in the phone, which is the best solution to avoid data theft in the case of lost phone.

The iCloud Security Code is a separate password that you can add yourself or use a lock screen passcode, which may be the third password you need to remember.
