The iOS running on the iPhone device is currently the safest system in the industry. However, the different habits of each user will also cause some security and security issues. This article will teach you how to improve the iPhone’s security settings. 15 You must learn to hide and cum to strengthen iOS security features.
1. Unlock password strength
Some iPhone users are afraid of forgetting the unlock password, so they will set the password to 000000, 654321 and other very simple passwords. It is recommended to change the unlock password to a mixed 6-digit combination. If you want more security, you can choose a combination of numbers and passwords. It is recommended that Face ID face unlock/Touch ID fingerprint unlock also be turned on together.
iPhone setting location: iOS “Settings”> “Touch ID and Passcode”> “Change Passcode”, there will be a “password option” at the bottom, you can change it
- Customized alphanumeric password (the most secure)
- Custom digital password (high security)
- 6-digit code (good security)
- 4-digit password (the password is weak and easy to crack)
2. Unlock screen permission setting
When the iPhone is not unlocked, do not open too many unnecessary permissions. You can find the “Allow access when locked” block through iOS “Settings”> “Face ID and Password” or “Touch ID and Password”. In the unlocked state, turning off the following permissions can prevent the iPhone from losing and causing excessive control over the unlocking screen permissions.
- Notification Center
- control center
- USB accessories
Among them, please do not turn on the “USB Accessory” function, which can prevent the device from being locked for more than one hour before you must unlock the iPhone to allow the connection, which can prevent being cracked by the GrayKey tool.
As for why Siri is not turned off? Mainly iOS 14 or above. Siri will automatically recognize the voice of the device owner. If someone shouts “Hey~Siri” to your device, the voice assistant cannot be woken up.
3. Erase iPhone data 10 times with incorrect unlock password
In addition, the “Clear Data” function in “Face ID and Password” or “Touch ID and Password” should also be enabled. The main reason for this security mechanism is to fear that if the phone is lost, people will try to guess randomly, just like the FBI finds other companies to crack Mobile phone incident.
In order to prevent the important data or photos in the iPhone device from being cracked, you can turn on this security protection mechanism. Remember to turn on the iCloud backup or use the iTunes backup from time to time to save the iPhone data smoothly.
4. Automatic screen lock time
In the “Screen Display and Brightness” function in the iOS settings, you can customize the “Auto-lock” time from the shortest 30 seconds to the longest 5 minutes. This function is mainly for users to customize the time for the iPhone to enter the standby state. It is not recommended for daily use Set it to “Never” to avoid forgetting to lock the iPhone to prevent the iPhone from being used by others when you leave your seat.
5. Hide App notification content
To avoid the notification push content of important iPhone messages will be directly displayed on the unlock screen, it is recommended to hide the notification content to prevent anyone from seeing the message content.
Change the iOS “Settings”> “Notifications”> “Show Preview” to “When Unlocked”. This feature is more convenient for Face ID users. The notification content will be displayed immediately as long as the face is scanned.
6. AppleID Double Verification
From time to time, Apple ID account secrets are stolen, credit cards are stolen, and the device is locked after being stolen by unknown users. These events often occur, and most of these reasons are caused by bad habits of users, such as frequent use. Piracy, cracking, installation of third-party apps from unknown sources, or mistakenly clicking on phishing letters and entering account secrets on phishing websites can easily lead to the theft of user accounts and secrets. In addition, if dual authentication is not enabled, it is easy to be stolen.
In Apple ID, the dual verification function is forced to be turned on, which can effectively prevent the account and password from leaking. The second authentication protection can make the account more secure.
As for some users who want to turn off Apple ID dual verification, when the dual verification function is turned on, it can be turned off within a week. After the time expires, it will not be closed. Mr. Crazy suggests that this security mechanism is not recommended to turn off.
7. Improve Safari browser privacy
If you borrow another person’s iOS device and want to browse the web through Safari, but don’t want to keep historical browsing data or log-in account and secret records, you can click the lower right corner of Safari to switch to the tabbed card mode, and click the “Private Browsing “You can.
8. Safari automatically closes tabs, browsing history and frequently visited websites
Using iPhone’s Safari to browse the web will cause more and more paging, causing many people to be too lazy to turn it off, and eventually turn it off. I will teach you a faster technique to let Safari automatically close the paging method. The techniques are as follows:
Generally, users who pay more attention to personal privacy will worry that the Safari records they have browsed will be found. I will teach you how to clear the Safari history browsing records on the iPhone, delete the frequently visited websites on the iPhone and turn off Siri suggestions. The setting techniques are as follows:
9. Automatically delete SMS and iMessage regularly
You don’t need to save it for a long time. You can set the retention time in the settings, which can be set to 30 days, one year or permanent. Once the time is up, the system will automatically delete these messages or iMessage conversation records to improve iPhone security protection.
If you want to automatically delete messages in your iPhone at regular intervals, you can set “Permanent, One Year, 30 Days” in iOS “Settings”> “Messages”> “Keep Messages”.
10. Prevent Apple personalized ads from tracking user habits
How to accurately deliver ads to the client? Advertisers will collect users’ habits and display them accurately. For example, I recently wanted to buy a MAC computer, but we only visited a few MAC computer stores. When the screen was just turned off and other webpages were opened, I found that the advertisements next to it would appear. Some shopping websites, MAC Computers, are offering special offers and messages, which are precisely delivered to the users in this way. How can we prevent such privacy habits from being collected? Perhaps it can be closed through the following steps.
- iOS “Settings”> “Privacy”> “Apple Ads”, turn on “Personalized Ads”.
11. Turn off unnecessary app location functions
Some apps do not require GPS positioning at all, and the positioning does not have any subsidy effect. Apps such as Music, Alipay, Open Air, PCHOME, etc. can turn off the positioning function. Go to iOS “Settings”> “Privacy”> ” Location Services”, select the apps to turn off location services, and change them to “Never”.
11. Restrict in-app purchases
Sometimes the device will be given to our children to play games, but we do not want our children to download APP or use the in-game purchase of virtual treasures. We can prevent such incidents by restricting access.
12. Lock the notepad
Many users are accustomed to using the built-in memo function of iOS to record account passwords or other important items. From iOS 9.3 and above, they can be locked through the memo. If you are interested, please see the tutorial below.
13. Email open attachment password
When there are sensitive messages in the email, in order to prevent it from being stolen during transmission, when opening the attachment, you can also jump out of the password prompt to open it.
14. Turn on Find My iPhone
What should I do when the iPhone, iPad, iPod, Apple Watch, MAC computer equipment is accidentally lost one day? If the “Find My iPhone” function was turned on, you can check the current device location through www.icloud.com. In addition to querying the device location, you can also play sound for the lost device, enter the lost mode, or Clear the device data control. In addition, this function can also prevent users who have seized or stolen the device from re-swiping and logging in to the iOS system. As a result, many users now inexplicably forget their AppleID and password, and no one can determine whether the device is genuine. If the device is purchased by yourself or you have found it, please go to Apple customer service to solve it directly.
Haven’t turned on this feature yet, please go to “Settings”> “iCloud” and turn on “Find My iPhone” immediately.
15. Don’t randomly click on unknown fishing letters
From time to time, many iOS users receive notifications from the App Store to unsubscribe emails. The emails pretend to be official subscription App monthly subscription email notifications, just like the style and layout actually sent by Apple. The purpose is to induce users to click the link in the letter directly, and to induce the input of Apple ID account information and payment information. The next time you receive a letter from Apple, it is recommended that you can check whether it is a legitimate email below.
