QTS-Unit 4-Question 2

Hello everyone,
There is a classroom resource that teaches students about creating strong passwords, passcodes or passphrases.

Overall, here are the key characteristics of a good, secure password:

  • At least 8 characters long. The longer the password – the better.
  • Use upper and lower case letters, numbers, and special symbols. Passwords that include mixed characters are harder to crack.
  • Does not contain easy to remember keyboard sequences.
  • Not based on your personal information.
  • The password is unique for each account you have.

Creating strong passwords, passcodes or passphrases

1. Create a password with at least 12 characters

Choose a password of sufficient length, between 12 and 14 characters is reasonable. Multi-character passwords are always more secure than passwords with fewer characters.

2. Combination of alphanumeric characters, symbols, uppercase letters, lowercase letters

Using a password consisting of different characters further increases the security and safety of your account. When using these types of passwords, it is difficult for hackers to “hack” your account password.

3. Create a rhyming password – Nursery Rhymes

The method that many people like to use and is also able to ensure good security policies on the Internet, even those that require passwords up to 15 characters long, is the rhyming password method.

You can rely on a verse, your favorite sentence, count the number of syllables, choose the first letter of each syllable to combine into a secure password. At the end of the password, you can add special characters such as exclamation point, question mark, etc.

For example: “ 1234Today it is very sunny. Kittens go to school with nothing .”

Is a verse familiar to you. So the password you can generate is:


It’s a strong password, 16 characters long including numbers, uppercase, lowercase letters and at least one special character.

4. A sentence from a song or the name of your favorite movie

A similar method is applied to a password taken from a verse in a song or movie title you like. Using a movie you like, but few people know will make the password even more secure. You can also replace it with the names or famous sayings of the characters, combined with the numbers specified for the first letter of a syllable to make the password more difficult to guess.

Example with a sentence of the character Al Pacino in the famous movie Scent of a Woman :

“If I were the same man that I was thirty years ago I’d take a flamethrower to this place!”

Replace the character ” t ” with the number 3 . This quote then becomes the password:

“ IIw36m3Iw3yaI3af33p! ”

The concept is basic cryptography 101, but here’s how to create a password that’s hard for hackers to hack into your account, but still easy for you to remember.

5. Use Technical Terminology

Another interesting method is to use technical terms in different professions. Each is an expert in his or her own career field. Based on that, you can choose a technical term that you are familiar with to create a strong password.

For example, if you are a nurse, or a doctor, phrases you may have to memorize for sure to work are:

” ARDS: Acute respiratory distress syndrome: acute respiratory distress syndrome “

You can replace the character ” a ” with a zero to create your own password like this:


This is just a 12-character password, but it’s hard to guess.

6. Your special day

Another method for creating strong and easy to remember passwords is mainly numbers. Of course, random numbers will make you forget. You should choose numbers based on dates that are particularly important to you.

For example, it was the day that you first got a bicycle. The day you kissed for the first time. The day you travel abroad…

So you have 3 important dates. You put those numbers on the same password and separate it with dashes, ending with a special character like a pound sign.

For example:


This password is up to 20+ characters, so it can only be used in systems that can handle very long passwords. 

7. Use keymap

Like the password method in smartphone models. You rely on the keyboard pattern to generate your own passwords.

6 ways to create the most secure password

With this method, you can draw recognizable images or letters on the keyboard. In the above case, the generated password is:


Using this method, you can change to lengthen the password. A hacker could potentially run an algorithm to figure out your password.

8. Make a rough password and divide it into parts

This method makes the password secure, but it is crude and easy to implement.

You create passwords and print them out into 2 different cards. Each separate card will be part of the password that you need to remember.

For example, your password might be ” 2BeOrNot2BeThatIsThe? “

So you’ll have a ” ThatIsThe? ” tag that reminds you of ” 2BeOrNot2Be ” and can keep it in two different places.

The value here is that even if someone finds your password part, they still won’t have the other half only you remember.

Passphrase (phrase) / Diceware

Passphrase (phrase) / Diceware

A passphrase password is a form of putting a hidden string of letters for a phrase to be used as a password, by stringing letters that are related to many words.

A good example is a popular Randall Munroe online comic from many years ago called XKCD which is also a way to set the “password” as XKCD.

However, this method is not a form of abbreviation for initial letters, but it only implies for an entire phrase by one or more words with no phonology or clear meaning.

In general, setting strong and easy-to-remember passwords according to the above methods is not necessarily “safe”. For example, if you use the same password for many accounts, if the password is leaked on any account, other accounts will easily be “intruded” illegally.

Ideally, for each account you use a different unique password, avoid phishing sites and keep your computer free of malware.

In a nutshell, the best password is one that has your unique personal touches. You can use the methods above or combine them to suit you best. Here are some suggestions to help you create a password that is strong and virtually unbreakable, but easy to remember for you.
