Complicate your password
Situation: The iPhone’s default 4-digit passcode setting isn’t the most secure. It’s not difficult for a stranger to watch you key your passcode in, then steal your phone. Tadah, he’s got access! Don’t worry, your iPhone’s got the answer. You can exchange the 4-digit code for a more complicated and thus secure password.
Solution: You can have my phone but not my password! To activate, go to Settings, then Touch ID & Passcode to disable Simple Password. After which, you’ll be prompted to enter your all-new password riddled with numbers that no one can crack with a glance. Ha!
Situation: You have a lot of secrets on your iPhone, information which should never be shared with anyone else. You panic when someone so much as glances at your phone while you’re texting.
Solution: Go to Settings, then Touch ID & Passcode, and scroll all the way down to find Erase Data. Enable that if you’re so paranoid about people accessing your top secret information. After 10 failed attempts to access your phone, all your data on your iPhone will be erased.
Bear in mind that you might try (and fail) to unlock your own phone while drunk and unwittingly destroy all your data. But that’s not a big deal if you regularly back up your phone, just a little bit of hassle that should teach you a lesson.
