You can set a passcode on your iPhone or iPod touch to keep your data secure. To do this:
- Go to Settings >General >Passcode Lock and enter a four-number passcode. (Please make it a little more challenging than “1234.”)
If security is very important to you, you may want to set the “Erase Data” option. When set, this option wipes your storage memory clean after 10 consecutive failed attempts to enter the passcode. To activate this:
- Go to the Set Passcode screen as described above.
- After you have entered a passcode and confirmed it, a second screen labeled “Passcode Lock” appears. Slide the “Erase Data” button to the on position
