Set a strong security code or use biometric security. A 4-digit passcode is easy to guess or remember, so use a mix of numbers and letters instead. To change your passcode, go to Settings > Face ID & Passcode/Touch ID & Passcode or Settings > Passcode.
- Tap Change Passcode, enter your current code, then tap Passcode Options to see more options. Finally, select the option for a Custom Alphanumeric Passcode.^{[1]XResearch source}
- Here are tips to help you create a secure password. If you suspect that someone has seen your code, change it immediately.
- Face ID and Touch ID are robust alternatives. However, when you restart your phone, a passcode is required. If you have a simple passcode, someone can easily reset your iPhone to get around the Face ID/Touch ID and still access your iCloud Keychain (for other passwords on your device) or your Apple Pay.
- If you're particularly worried about your data, don't type your password in public. Thieves can easily remember shorter passcodes, so typing in a 4-digit passcode publicly makes your data more vulnerable to hacking.

Don't solely use iCloud Keychain.

Download Article

Keychain makes it so you don't have to remember all of your passwords, but it's more valuable to thieves. If a thief gets into your iPhone and you've saved all of your passwords in Keychain, the thief can access everything on your iPhone and every other website and app with a password you've stored in Keychain. If you have Touch ID or Face ID, iCloud Keychain is safer, but not the safest password manager. Protect your data from thieves by using a secondary password manager.
- A simple search on Google shows you all the different password managers out there, like NordPass.
- iPhones with Face ID and Touch ID offer Passkeys, which will ask for two-factor authentication the first time it's used.^{[3]XResearch source}

6

Control what shows up on the locked screen.

Download Article

Hide features that make your iPhone vulnerable without entering a code. If, for example, you have Control Center enabled on your locked screen, someone can easily connect via Bluetooth to an unreliable connection without knowing your passcode. Make sure you don't leave openings for other people to take advantage of, including calendar dates and appointments.
- You can disable and enable what appears on your locked screen by going to Settings > Face ID/Touch ID & Passcode

7

Use Safety Check.

A Safety Check will quickly identify what data you share with others. If any holes are found in your security, Safety Check makes it easy to protect your data from thieves instantly. To do a safety check, go to Settings > Privacy & Security > Safety Check and follow the on-screen instructions.^{[4]XResearch source}
- Protect your data from thieves by using Safety Check whenever you download a new app or notice suspicious activity on your phone.

8

Check your App Privacy Reports.

Download Article

See how apps on your iPhone use the permissions you granted them. You can also see how they use your internet connection. If an app is shady, uninstall it to protect your iPhone data. To see this information, go to Settings > Privacy & Security > App Privacy Report.^{[5]XResearch source}
- If you do not see the data that you expected, open the App Store and search for the app's name. Then, you can look on the app's product page for information about the developer and a submitted summary of the app's privacy practices, including the collected data.

9

Enable Mail Privacy Protection.

Download Article

This makes it harder for others to discover your activities in the Mail app. Mail Privacy Protection hides your IP address so others can't determine your iPhone's location. To turn this on, go to Settings > Mail > Privacy Protection and toggle it on.
- If you subscribe to iCloud+, you can enhance this privacy protection more by hiding your email address and instead using unique addresses that forward emails to your personal account.^{[6]XResearch source}

10

Browse privately with Safari.

Download Article

Hide your activity and personal information using privacy settings in Safari. There are a few different tools that you can use to keep yourself safer when you're browsing the internet. Go to Settings > Safari to turn these options on:
- Prevent Cross-Site Tracking – This is on by default and prevents sites from knowing which sites you've visited consecutively.
- Hide IP address – This is on by default and hides your IP address from known trackers. If you have iCloud+, this feature is enhanced, and you can be assured that your IP address is always hidden.
- Block All Cookies – Turn this feature on if you don't want your iPhone to keep a cache of cookies for every site. Turning this off means that websites won't store your login information.
- Fraudulent Website Warning – Safari displays a warning if you visit a known and suspicious website. This is enabled by default and is good to keep on if you want to get alerted that sites you visit are suspicious.
- Privacy Preserving Ad Measurement – Turn this setting off if you want sites to be able to see your personal information and give you more personalized ads.
