How to create a strong password – Password strength
Password strength is a term used to describe how difficult it is to discover a password. That is, the password is difficult to guess, difficult to detect the password.
Password strength is a term used to describe how difficult it is to discover a password. That is, the password is difficult to guess, difficult to detect the password.
The required quality of the password depends on how good 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 on the number of logins from 1 IP address, or adds a captra authentication step if it is wrong more than n times…
Main content of the article:
* What is a strong password?
A password is considered strong if it is guaranteed to be difficult to guess, and cannot be detected by trying different scenarios (read more Brute Force, What is a Brute Force attack?)
To set a strong password:
* Passwords over 12 characters (The longer the better)
* Include lowercase letters, uppercase letters, numbers, special characters.

Examples of strong passwords are:
A strong password is one that is long enough, is random, or otherwise can only be devised by the person who chooses it, so that guessing it would take longer than a cracker would. password lock ready to spend to guess it. 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 is not worth a few seconds for a computer to guess, while a password that manages access to a major bank’s electronic money transfer system may 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.
t3wahSetyeT4 — case sensitive and alternating digits
4pRte!ai@3—case sensitive, alternating digits, punctuation, and a “special” character
MoOoOfIn245679—case sensitive, alternating digits
Convert_100£ to Euros!—phrases can be long, easy to remember, and contain extended symbols for increased strength, but some weaker password hashing methods may depend on frequency analysis
1382465304H—a string of numbers ending with a character
Tp4tci2s4U2g!—A blend of characters with different case letters, numbers, and punctuation. It’s easy to remember because it’s the beginning of “The password for this computer is too strong for you to guess!”
5:*35pm&8/30—Phone time and date with two random “special” characters
EPOcsoRYG5%4pp@.djr—uses multiple factors including capitalization and special characters
In the cryptographic context, terms can have considerable precision. For example, passwords are generally not suitable for use as encryption keys. Note, however, that even a ‘strong’ password can be stolen, defrauded or coerced into disclosure by the user, or obtained from a key-monitoring program, intercepted while in transit. transmitted, or accidentally discovered by someone else.
If you are using a hosting provider but set a weak password, change it to a strong password right away to avoid password detection. Detecting passwords is the oldest “hacking” way, don’t let the “ancient people” harm you 🙂
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—too predictable
1234—too predictable
abc123—too predictable
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

This brief list is just the simplest examples; there are many other examples that are considered weak for the same or similar reasons as above. In addition, any password given as an example is considered weak, simply because everyone already knows it.
3.8% of passwords are single words found in the dictionary
