iPhone has several security options such as FaceID, Passcode, alphanumeric and more. The current iOS version allows you to unlock your iPhone with FaceID even when wearing a mask.

Why Should you Change your iPhone Passcode frequently?

Guessing an iPhone passcode should not be that tough for geek heads; most people tend to use their birthday, sometimes of their relatives and most times of their pet. Though Apple has quite a secure environment, it can do nothing when your Ex-person have your iPhone passcode or, in the worst case, shares any of your Apple subscriptions. If someone is sharing your iCloud based subscriptions such as Apple TV, iTunes, or anything alike, they have an excellent opportunity to change your iPhone and iCloud passcode easily. So, it is in the best interest to keep changing your iPhone passcode and iCloud account passwords. iCloud accounts can be used alongside iTunes to delete information from your account or permanently lock you out.

Fancy apps such as change iPhone keyboard colour or status bar icon changers have payloads and keyloggers hidden in them; such apps can easily sniff your passwords and compromise your iPhone security.

You can pen down those 4-6 digits in your flap diary (not a good option) or best memorise them. Avoid using numbers that depict your real-life connections, and in case you forget them, you can always have a chance to erase your locked iPhone or recover your device using iTunes.

  1. 4 Digits (4 digit passcode)
  2. 6 Digits (6 digit passcode)
  3. Custom Alphanumeric (Combination of numbers and digits)
