Password attacks are to a great degree common, as they are anything but difficult to perform and regularly result in a successful intrusion. There are two basic types of password guessing that can be performed: brute force or dictionary-based attacks.



What Is Brute Force Attacks

Brute force, refers to trying as many password combinations as possible until hitting on the right one.  It is a method commonly used to obtain password. While the exact number of characters in a password is usually unknown, most passwords can be estimated to be between four and 16 characters. Though massively large, the number of possible password combinations is finite and is therefore vulnerable to brute force attack.

Brute force attempts to discover passwords usually involve stealing a copy of the username and hashed password listing and then methodically encrypting possible passwords using the same hashing function. If a match is found, then the password is considered cracked. Some variations of brute force techniques involve simply passing possible passwords directly to the system via remote login attempts. They tend to be extremely slow.





What Is Dictionary Based Attacks

Simple passwords such as any individual word in a language make the weakest passwords because they can be cracked with an elementary dictionary attack. In this type of attack, long lists of words of a particular language called dictionary files are searched to find a match to the encrypted password. More complex passwords that include letters, numbers, and symbols require a different brute force technique that includes all printable characters and generally take much longer to run.

My passwords have usually been quite long, which kind of annoys me - but it's better than having your accounts online invaded continuously.

A strong password consists of at least six characters (and the more characters, the stronger the password) that are a combination of letters, numbers and symbols (@, #, $, %, etc.) if allowed. Passwords are typically case-sensitive, so a strong password contains letters in both uppercase and lowercase.

I would say at least ten characters these days, mixed with the letters/numbers/symbols/etc. The more scrambled, the better. Pizza Time!

@Dr Jay do you know good website we can use to check password crack time?

For that: https://www.betterbuys.com/estimating-password-cracking-times/ (Also this is a secure site, which is good!)
