Password policies and best practices in Cybersecurity - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the main purpose of a password policy?

A password policy sets rules to create strong passwords and protect accounts from unauthorized access.

beginner

Why should passwords be a mix of letters, numbers, and symbols?

Mixing letters, numbers, and symbols makes passwords harder to guess or crack by increasing complexity.

beginner

What is two-factor authentication (2FA)?

2FA adds a second step to login, like a code sent to your phone, making accounts more secure even if the password is stolen.

beginner

Why is it important to avoid using the same password for multiple accounts?

If one account is hacked, using the same password everywhere lets attackers access all your accounts easily.

beginner

What is a passphrase and why is it recommended?

A passphrase is a longer password made of several words. It is easier to remember and harder for attackers to guess.

Which of the following is the strongest password?

A P@ssw0rd123!

B 123456

C password

D qwerty

Option A uses letters, numbers, and symbols, making it much stronger than common or simple passwords.

What does 2FA stand for?

A Two-Face Authorization

B Two-Factor Authentication

C Two-Fold Access

D Twice Fast Access

2FA means Two-Factor Authentication, adding an extra step to verify your identity.

Why should passwords be changed regularly?

A To confuse the user

B To make login slower

C To keep accounts secure if passwords are leaked or guessed

D To avoid remembering passwords

Regularly changing passwords helps protect accounts if old passwords are compromised.

Which practice helps protect your accounts best?

A Using unique passwords for each account

B Using the same password everywhere

C Writing passwords on paper

D Sharing passwords with friends

Unique passwords prevent attackers from accessing multiple accounts if one password is stolen.

What is a recommended minimum length for a strong password?

A 3 characters

B 4 characters

C 1 character

D 8 characters or more

Passwords should be at least 8 characters long to be harder to guess or crack.

Explain why using a passphrase can be better than a simple password.

Think about how length and complexity affect security and memory.

Describe the benefits of enabling two-factor authentication on your accounts.

Consider what happens if someone knows your password but you have 2FA.
