Always look for the password difficult to guess and could not be easily compromised. Usually, the best method for generating passwords is to select a sufficient number of randomly selected characters. The problem is that such passwords are usually very difficult to remember.
To create a random password memory-friendly, another method is sometimes used, i.e., random words or syllables are used instead of random letters. We can also find users who prefer to use mnemonic phrases that have random letters at the beginning of every word.

Sometimes personal mnemonics are used. It involves things memorable for you, but not for others. Take this password for example IvLwIw16. It derives from "I visited London when I was 16." It is the user's own memory and nothing else. That makes it easier to remember and difficult for others to crack.
Some software programs have now been developed to generate random passwords containing a varied set of characters that include lowercase and uppercase letters as well as numbers. It is difficult to crack or guess due to an optional combination of lower- and upper-case letters and numbers.
Some programs give you the option to generate fixed or variable length passwords. Sometimes a high-quality number of pseudorandom generators is used which offers five methods for a generation: a) automatic generation where the user can choose the contents,
b) generation of masked which specifies the patterns describing the password,
c) dictionary mode where he grabs random passwords from a file the user specifies,
d) pronounced mode for easy to remember passwords and
e) the character list mode for generating passwords consisting of a chosen list of characters.
All modes can choose lowercase, uppercase, or mixed-case letters. Some generators create purely random passwords while others generate passwords based on a list of words. Although more secure, purely random passwords tax the user's memory. Passwords based on wordlist, on the other hand, are more memory-friendly.
