    MFA has become one of the strongest defenses against password-based attacks such as brute-
                      force attempts, credential theft, and phishing. It provides  enhanced  protection  by  confirming
                      identity in more than one way, making unauthorised access extremely difficult.

                      Passphrases: The Sentence as a Password

                                       “Trying to remember a complex string of letters and symbols like XyZ!9@aP is

                                                       not easy! Its easier to remember a sentence!”

                      A passphrase is a type of password that
                      resembles a short sentence or meaningful phrase.
                      It is designed to be simple to recall while being
                      extremely difficult for attackers to guess or crack. Unlike short passwords made of random letters
                      or numbers, a passphrase is longer and naturally more complex, which greatly increases security.

                      For example, instead of using a simple or predictable password, a strong passphrase such as
                      MyCat!Loves#Walks@2025 can be used. This passphrase is effective because:

                           It is long, which makes brute-force attacks much harder.
                           It contains a mixture of uppercase and lowercase letters, numbers, and special characters.

                           It forms a meaningful phrase, which is easier to remember than a random combination.

                      Passphrases are widely recommended in modern cybersecurity because longer and meaningful
                      strings provide stronger protection against password-guessing techniques, dictionary attacks,
                      and automated cracking tools.

                                                                                                  21 st
                                               CREATE A STRONG PASSPHRASE                        Century   #Critical Thinking
                                                                                                  Skills

                      Think of an interesting, funny, or easy-to-remember sentence.
                      Example: A smart puppy ran across the playground today.

                      Convert this sentence into a secure passphrase by adding symbols, replacing certain letters with numbers,
                      and mixing uppercase and lowercase letters.
                      Example: A_sm@rt_puppy_r@n_@cr0ss_th3_pl@ygR0und_t0d@y!
                      Now, create two or three more passphrases for different imaginary accounts to build confidence in forming
                      strong, memorable security phrases.
