Posted by Aimee , Oct 01, 2020

"I use the iPhone SE. Three hours ago, I accidentally clicked on a link posted by an unfamiliar Twitter user. It jumped to a page with inappropriate content. I am worried about this. The fake link is very dangerous. It will cause the iPhone to be infected with a virus. So I reset the iPhone. Then I changed the passwords of the screen lock, Apple ID, Instagram, Facebook, WeChat, etc. 
I have read some articles about iOS devices being hacked. Most people say that iOS is very safe. I also did not find any abnormal applications on the task manager. However, I am wondering if this link will install malware or spyware on my iPhone? Thanks in advance for your help. "
Smart devices store personal and sensitive data, so they are the main targets of hackers and thieves. Thanks to the high security of the iOS system, Apple users don't need to worry too much. However, this is not foolproof. If you need more ways to protect your credit card, bank account, e-mail, SMS, and other private data, then you can get help in this article. These solutions are not only applicable to the iPhone but also to other iOS devices.

Activating the function of Find My iPhone is an important way to deal with hackers. When your phone is lost, you can use this function to locate your device or remotely wipe data. This way you will prevent others from stealing your private data.
- Tap the "Settings" app on the Home page. Then, tap your name at the top of the screen.
- After clicking "iCloud", pull down and click "Find My iPhone". Then click "That".

In order to better discover stolen or lost devices, it is recommended to enable the "Offline Finding" function. This allows you to clear the data on the iPhone in time.

2. Activate Erase Data

To improve the security of the iPhone, it is necessary to turn on "Erase Data", which can automatically wipe all files on the phone when the wrong password is entered ten times.
- Find and tap the "Touch ID & Passcode" item in "Settings".
- After entering the password, scroll down to the bottom to activate the "Erase Data" feature.

3. Set up Touch ID or Face ID

Touch ID and Face ID use unique biometrics as the passcode, which helps increase the security of the iPhone.
Set up Face ID
- Go to "Settings" on the Home page and find "Face ID & Passcode".
- After clicking "Set Up Face ID", hold the iPhone vertically.
- Click "Get Started". Then perform a face ID scan. After repeating it once, click the "Done" button.

Avoid opening unknown or unrecognized URLs. Although hackers cannot directly invade your phone through these links, they will create some unknown risks. It is good to maintain a cautious attitude.

There are potential security issues with enabling glanceable notifications and access permissions on the iPhone screen. To disable lock screen access, you can do the following:

- Tap the "Settings" icon on the Home screen.
- Click "Privacy", then tap any app to view the granted permissions.

Check App permissions

If necessary, you can revoke some app permissions for an app.

- Select the photo you want to share and click "Options".

- Go to "Touch ID & Passcode"/"Face ID & Passcode" from "Settings".
- Disable the "Allow access when locked" item.

9. Change the password regularly

Changing the passcode regularly and setting a complex password can better protect the iPhone.
