Unit 4


  1. Create or find a classroom resource that teaches students about creating strong passwords, passcodes or passphrases.

In order for my students to understand the ways to make up their strong passwords, passcodes or passphrases, I would introduce them respectively from the most familiar to the least familiar as follow:

+ Strong passwords:

Strong passwords are the ones that are difficult to guess and often require a mix of uppercase, numbers and symbols. Strongest passwords require a minimum of 16 characters, however, a password between 8 and 16 characters is said to provide good level of security.

FOR EXAMPLE: AN ACCOUNT’s password CAN BE: 1590ProSecurity#

+ Passphrase

A passphrase is similar to a password in usage, but it is longer and more secure. Most passphrases have a minimum requirement of 14 characters. A passphrase can be a phrase that the user can easily remember is difficult to be guessed by others. Passphrases can have upper and lower case characters, blank and special characters.

Passphrases create greater security and more convenience:

  • Contains at least 4 words or 14 characters
  • Combine with two factor authentication
  • Unique for each website or service
  • Use a Password Manager
  • Complex, use capitals, punctuation and symbols
  • Avoid famous phrases or lyrics
  • Make it meaningful to you to make it easy to remember

FOR EXAMPLE: A passphrase CAN BE: ITrooom2021@

+ Hashing Passwords

To protect passwords, cyber security professionals can add another layer of security to passwords by converting them to a random string of letters, numbers, characters using complex computer algorithms. This process is called hashing. With hashing, even if the stored passwords are leaked, they are not in a usable form. A good hashing algorithm ensures that the original password should not be reversed using the hash. MD5, SH-1 were the most popular hashing algorithms which are now replaced with SHA-256 as the current preferred hashing algorithm in modern encryption.
