If someone needs to borrow your phone and you are uncomfortable because of all the personal information in your phone, there is a way to restrict the person to only the app they need to use.

Here are the simple steps to set up this feature.

1. Go Settings/Accessibility/Guided Access
2. Turn on Guided Access
3. Tap on Passcode Settings and set a Guided Access Passcode
4. Decide if you want to Face ID, PIN Code, or Touch ID to end the Guided Access with a double-click
   

The next time someone wants to use your phone to make a call, for example, open the Phone app. Depending on which model of phone, you have to Triple-click the Home button or the Side button.

A menu will appear. Tap on Options to set various functions. Then tap on Start. Then hand the phone to the person, and they will only have use of the Phone app.

To end Guided Access, double-click the Home button or Side button. You will then need to provide the PIN, use Face ID or Touch ID to finish the procedure.
