Brute Force Attack

Any password can be cracked no matter how complex it is. Hackers use computer programmes to try different password combinations until they successfully gain access. Since the computing power keeps enhancing nowadays, the time needed for hackers to crack a password gets shorter.

Safe Password Tips

1. Do not use personal information, such as name, identity card number, vehicle registration mark, telephone number or date of birth as your password.
2. Do not use password made up of the same character.
3. Do not use characters that are in order, such as “abcdefg” or “23456789”.
4. Do not use password made up of characters next to each other on the keyboard, such as “qwertyui” or “!@#$%&*()”.
5. Do not use words that can be looked up in a dictionary, e.g. “Password”, be it in English or other foreign languages, or their reversed spelling.
6. Do not use common acronyms or abbreviations, such as “HKSAR” or “MTR”.
