How to create a strong password – Password strength
What is a strong password?
Strong passwords are the ones that are difficult to guess and often require a mix of uppercase, lowercase, numbers and symbols. Strongest passwords require a minimum of 16 characters, however, a password between 8 and 16 characters is said to provide a good level of security.
The required quality of the password depends on how well the password system is to limit the number of guesses of a member’s password, whether from someone who knows the member well, or from a computer that is probing. millions of possibilities. A good system has a limit to the number of logins from 1 IP address, or adds a captra authentication step if it is wrong more than n times…

The time to be deemed too long will vary depending on the attacker, the attacker’s resources, the ease of access to tryable passwords, and the value of the password to the attacker. . A student password isn’t worth a few seconds for a computer to guess, while a password that manages access to a major bank’s electronic money transfer system can be worth weeks or even weeks. months to guess.
It would be a mistake to use the passwords listed below: they are publicly available, so they are weak. All comments on password strength assume that they are unknown and unwritten. While similar passwords, or based on the same principles, will be strong enough, assuming you don’t read them.

Trong ngữ cảnh mật mã hóa, các thuật ngữ có thể có độ chính xác đáng kể. Ví dụ như, mật khẩu nói chung không phù hợp khi dùng làm khóa mã hóa. Tuy nhiên, chú ý rằng thậm chí một mật khẩu ‘mạnh’ vẫn có thể bị đánh cắp, lừa gạt hoặc ép buộc để người dùng phải lộ ra, hoặc bị thu thập từ một chương trình theo dõi bàn phím, bị chắn khi đang truyền đi, hoặc bị một người khác vô tình tìm ra.
Nếu Bạn đang sử dụng host gia re mà đặt mật khẩu yếu, hay thay đổi thành mật khẩu mạnh ngay để tránh bị dò mật khẩu nhé. Dò mật khẩu là cách “hack” cổ xưa nhất, đừng để cách của “người tiền cổ” làm hại Bạn nha 🙂
What is a weak password?
A weak password is a short, common password, a system-provided default, or something that can be guessed quickly by performing a brute force attack using a subset of all possible passwords, such as dictionary words, proper names, username-based words, or common variations of those words. Passwords that can be easily guessed based on knowledge of the user, such as date of birth and pet name, are also considered weak.
Examples of weak passwords:admin—quá dễ đoán
minh—common proper name
password—easily guessed, very often used
p@$$//0rd — leet and plain-character cipher both pre-programmed in jailbreak tools
rover—common pet name, also a dictionary word
12/3/75—date, may be important to the individual
December12—It’s very common to use a mandatory password change date
nbusr123—probably a username, and if so, extremely predictable
asdf—sequence of characters in various keyboards
qwerty—a string of characters that are contiguous in many keyboards
aaaa—repeated, predictable characters
