Protecting your mobile device with a passcode is important in order to protect the information saved in the device.
In mobile phones, the SIM card is usually protected with a PIN code, which prevents unauthorised phone calls. PIN codes should also be used in iOS devices, and it is recommended that you change the default code.
- Tap Settings > Phone and check that the PIN code for the SIM card is active.
- Tap Change PIN and enter the current PIN code and then the new PIN code.
Quick help
Enabling the device passcode
Keeping the device passcode activated in iPad or iPhone is very important. When the device passcode is used, the information in the device is protected with strong device encryption and no one is able to use the device without entering the passcode.
- Tap Settings > General > Passcode.
- Tap Turn Passcode On and create a passcode which is difficult to guess.
- To improve information security, you can switch off the Simple Passcode setting. This allows you to also use letters and special characters in the passcode.
- Activate Erase Data, meaning that the device information is erased if an incorrect passcode is entered too many times.
iCloud: Find iPhone and Activation Lock
The newest iOS versions allow you to prevent the erasing and reactivation of a device by using the Find my iPhone feature of the iCloud service. In spite of its name, Find my iPhone also works in iPad and iPod touch.
- Tap Settings -> iCloud and sign in using your Apple account or create an Apple account. (The Apple account is used for downloading applications from App Store, for example).
- Activate Find my iPhone.
You can then test the service by logging in at iCloud.com with your Apple account.
Factory reset
Note! Restoring the factory settings will erase all data on the device. Back up your data before doing so!
If there are problems with your iOS device, a factory reset is the last resort. Before that, you should reboot your device, reset network settings Settings > General > Reset > Reset network settings and update your device with the latest iOS.
Restore factory settings
- Tap Settings > General > Reset > Clear all content and settings.
- Enter the access code set on your iOS device.
- Enter the Apple ID and password used in iCloud, if the Find my iPad feature is enabled.
- Note! If iCloud and its Find my iPhone/iPad is enabled, the device cannot be unloaded. So if you want to access a device that was used by another person, you need to make sure that they log out of iCloud first. For example, if an employee has changed jobs, they can go to their Apple ID to uninstall their device by logging into iCloud.com. See Apple's guide at https://support.apple.com/kb/PH2702?locale=en_US&viewlocale=fi_FI
- The device restarts itself and clears the data.
