How powerful is relatively easy to do first is to change your Apple ID password. Apple ID is an email address and password used to gain entry into the main service Apple, including iCloud, iOS App Store, and iTunes.
When replacing the Apple ID password, make sure that you enter the new password is 8 characters (digits) in which there is at least 1 letter, 1 uppercase letter, and does not contain many of the same characters in sequence. It is better if the password has not been used previously and is not associated with the username that you use.
One of the best ways to get random and strong passwords is to randomly select a sentence. Of the sentence, you can delete the entire first letter in each word. After that, just enter the numbers, capital letters, and symbols. That way hackers can not apply the method of 'Social Engineering' on your Apple ID or iCloud.

When you include people who are loyal and love to lend an iPhone on a friend or family, your device may require a password entry at the lockscreen is often called a 'passcode'. Although it looks trivial, the passcode is one of the best ways to secure a smartphone when the iPhone is not accidentally lost or stolen.
Like the Apple ID password, you better create a passcode with a combination of numbers or letters that are quite 'random'. Avoid the use of the plural is used as the password 1111, 1234, or easily guessed words like LOVE and PASS.
Once you put a password on the iPhone try the password is not known by anyone else, including your own family. Apple also does not recommend users to send a passcode Apple ID and password via e-mail, including social networking.
If at any time you are aware if the password is already known by others try to immediately replace it. This also applies to the Apple ID password.
