Step 2：Tap Passcode Settings, then tap Set Guided Access Passcode.
Step 3：Enter a passcode, then re-enter it. From here, you can also turn on Face ID or Touch ID as a way to end a Guided Access session.
Step 4: Open the app that you wish to restrict and tap the Side (iPhone X or later) or Home (iPhone 8 or earler) button three times.
Step 5: The screen area will appear within a frame. Circle any areas of the screen that you would like to make inaccessible.
Step 6: Tap on Options in the bottom left corner to choose whether or not you want to grant access to the Sleep/Wake button, Volume buttons, touch screen, and motion. Tap Done to save your selections.
Step 7:Tap on Start at the top of the screen to begin Guided Access.
