Nowadays, iPhone becomes more and more popular. To ensure iPhone security, users should take a series of measures, among which enabling passcode lock is the most basic one. Nevertheless, many users always hesitate to enable this function since they want to use iPhone more conveniently. Here, we strongly suggest enabling Passcode Lock and setting it work automatically, which can increase difficulties in unauthorized people’s operating our iPhone maliciously. Detailed steps to enable passcode lock are as follows: Select “Settings” – “General” – “Passcode Lock” respectively and tap the functional button “Turn Passcode On”. Then, you are required to enter a four-digit passcode twice. Note: passcode should be
difficult to guess, and passcodes like 1111, 2222, 5555, 1234, and 1988 (birthdate) are not suggested. In the process of enabling passcode lock, users need to select a defined period of time to lock iPhone, like the left screenshot shows. Users are highly recommended choosing 1 minute which is also the default value. It is the safest setting since it can make iPhone furthest locked so as to avoid mistaken and malicious operation. Furthermore, users should turn on the function “Erase Data”, which can erase all data after 10 failed passcode attempts. Some people may hold such a worry that all data are deleted by naughty child or erased by mistake. As a matter of fact, there is no need to worry about mistaken erasure. After several failed passcode attempts, users are not allowed to enter passcode in 1 minute, delaying to 5 minutes. At last, it will increase to 30 minutes. It is believed that no person has enough time to perform 10 failed passcode attempts unless his iPhone is lost or stolen.
