Everyone should know that iPhone is more like a mobile computer, means it has its own operating system. every operating system will have it’s admin account, and in iphone (or unix) we call it a ‘root account’. by having this particular account accessible to all, you are putting your phone in danger. the most basic thing to secure this account is to have the password ONLY to yourself. below is a step-by-step guide to help you in changing the default password for iphone.
standard password for ALL iphone’s root account is alpine. earlier version of iphones use ‘dottie‘ as password.
1. by default when you open your terminal you will login to normal (user) account. login to root first before you can change the password.
to do this type ‘su‘ and enter (return). the system will ask you for password. type in ‘alpine‘ and enter (return).
*notice your user prompt shows ‘#‘ symbol instead of ‘$‘. This shows that you already login to root account (plus the word ‘root’ besides it).
2. type ‘passwd‘ to change your password. the system will ask you to put in your new password, twice. just make sure you type something that you can remember, secure,
and not too easy for others to guess.
and you are done.
