Set a Passcode Lock on iPhone, iPod touch, and iPad
- Press Settings > Passcode Lock.
- Enter a 4-digit code that will serve as your passcode.
- Enter your passcode again.
Your device now requires your passcode to unlock it. You must enter your passcode when you turn on the device or press the Wake button.
On iPhone, you do not have to enter your passcode to answer calls or make emergency calls. You must enter your passcode to make normal calls.
By default, if you have a passcode set for iPhone, iPod touch, and iPad, you must enter it immediately after turning on the device or pressing the Wake button.
You can change the length of time your device is idle before your passcode is required. For example, you can set the device to only require a passcode after it has been idle for more than five minutes.
To change the length of time before your passcode is required, do the following:
- Press Settings > Passcode Lock > Require Passcode.
- Select a length of time. Shorter times are more secure.
Setting up lock-screen security on Android
- Go to the Settings menu on your device.
- Scroll down until you find “Security” or “Security and Screen Lock” and tap it. This is typically located under the “Personal” section on Android 4.2 or higher.
- Under the “Screen Security” section, tap the “Screen Lock” option. By default, this option is set to “Slide,” which means no password or pattern is needed.
- From here, select which lock type you want to use, whether it’s Pattern, PIN, or Password.
- Pattern: swipe to draw an unlock pattern you want to use. It will then ask you to draw that pattern again to confirm.
- PIN: insert a 4-digit PIN that you’re sure you’ll remember. Re-enter the PIN to confirm.
- Password: type the password you’re comfortable with. The password must be at least 4 characters, must be no more than 17 characters, and must contain at least 1 letter. Use an alphanumerical (letters and numbers) password with symbols that’s at least 8 characters long for ultimate security, but anything will do. Re-enter the password to confirm.
No matter which option you chose, you should now be asked to enter your pin every time you wake your device. From here, you’ll want to explore different options you have for making it less annoying to access your phone.
Check for settings that will allow you to set a time limit that will keep your phone unlocked until that timer is up. You should also have settings for locking the device anytime the power button is pressed, regardless of what you have the timer set to.
This is useful for those times where you anticipate checking your phone often in a short period of time (for instance, if you’re texting back and forth with a friend), but don’t want to have to use access codes to unlock your phone every single time.
Make sure you know your Google account password
This is important because if you ever forget your PIN, password, or pattern, you’ll be locked out after a number of incorrect tries, and your only option to get back in is to use your Google password (otherwise, you’ll have to resort to a factory reset, which wipes all your data).
