There are many secure ways to lock your Apple iPhone.
- Passcode: This is an easy and effective way to lock your iPhone. To protect your iPhone, you will need a passcode. This is a code that can be set up numerically. Go to Settings > Passcode & Face ID (or Touch ID and Passcode if you don’t have FaceID) > Turn Passcode on. When you are prompted, you will be asked to enter a 6-digit passcode that you will need every time you unlock your iPhone.
- Fingerprint: Most iPhones with Touch ID (or Face ID & Passcode) have a fingerprint sensor that allows you unlock your iPhone by using your fingerprint. Go to Settings > Touch ID & Touch ID Passcode (or Face ID & Touch ID Passcode if you don’t have FaceID) > Set up fingerprint unlocking. Follow the prompts for adding your fingerprint to the iPhone. After your fingerprint has been added, you can unlock the iPhone by simply touching the fingerprint sensor.
- Face ID: This facial recognition system allows you to unlock your iPhone with your face. This feature is now available for iPhones with newer models and it is extremely accurate and secure. Go to Settings > Face ID and Passcode > Turn On Face ID. Follow these steps to set up facial recognition data. After your face has been added, you will be able to unlock your iPhone simply by looking at it.
- Two-factor authentication: To unlock your iPhone, you will need to enter a code along with your fingerprint or passcode. This code is sent to you via text message, email or phone. Go to Settings > Face ID and Passcode (or TouchID & Passcode if you don’t have FaceID) > Turn on two-factor authentication. Follow these steps to activate your two-factor authentication.
- You can also set your iPhone up to erase all data after a certain amount of failed passcode attempts. Go to Settings > Face ID and Passcode (or TouchID & Passcode, if you don’t have FaceID) > Erase data. Turn the switch on and select the number of failed passcode attempts to erase the data.
Your personal preferences and needs will determine the best way to secure your iPhone. Passcode provides basic security and is simple and efficient. Face ID and fingerprint are more secure and convenient options. Two-factor authentication provides additional security. The erase data feature protects your data in the event that your iPhone is stolen or lost.
