Your smartphone is a valuable device that contains a wealth of personal information. It’s important to take steps to protect your phone from unauthorized access, and one of the best ways to do that is to require a passcode, biometric fingerprint, or Face ID.
What is a passcode?
A passcode is a short sequence of numbers or letters that you enter to unlock your phone. It’s important to choose a strong passcode that is difficult to guess. Some tips for creating a strong passcode include:
- Using a combination of numbers, letters, and symbols if you can.
- Avoiding using personal information that is easily guessed, such as your birthday or your address.
- Changing your passcode regularly.

What is biometric authentication?
Biometric authentication uses your physical characteristics, such as your fingerprint or face, to identify you. This is a more secure way to unlock your phone than a passcode, because it’s much harder for someone to steal your fingerprint or face than it is to guess your passcode.
Why should you require a passcode, biometric fingerprint, or Face ID?
There are several reasons why you should require a passcode, biometric fingerprint, or Face ID on your phone:
- To protect your personal information. Your phone contains a wealth of personal information, including your contacts, email, photos, and financial information. If your phone is lost or stolen, anyone who finds it could access this information if it’s not protected by a passcode or biometric authentication.
- To prevent unauthorized access to your apps. Many apps require a passcode or biometric authentication to access them. This helps to prevent someone from accessing your apps without your permission.
- To protect your phone from malware. Malware can be used to steal your personal information or lock your phone. A passcode or biometric authentication can help to protect your phone from malware.
How to set up a passcode or biometric authentication
To set up a passcode or biometric authentication on your phone, follow these steps:
- Go to your phone’s settings.
- Tap on “Security” or “Biometrics & security.”
- Tap on “Screen lock” or “Face ID & passcode.”
- Enter your current passcode, if you have one.
- Tap on “Set passcode” or “Add a fingerprint or Face ID.”
- Follow the on-screen instructions to create a passcode or set up biometric authentication.
Additional tips for protecting your phone
- Keep your phone’s software up to date. Software updates often include security patches that can help to protect your phone from malware.
- Be careful about what apps you download. Only download apps from trusted sources, and be sure to read the app’s permissions before you install it.
- Use a VPN when you’re connected to public Wi-Fi. A VPN can help to protect your privacy and security when you’re using public Wi-Fi.
- Be careful about what information you share online. Don’t share your personal information, such as your Social Security number or your home address, online unless you absolutely need to.
