Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Using a long passphrase that includes symbols and numbers
Why this is correct
Correct: a long passphrase with complexity is strong.
- ✗
Using a password with 8 characters including letters and numbers
Why it's wrong here
8 characters is too short; best practice recommends at least 12.
- ✗
Reusing the same password across multiple sites
Why it's wrong here
Reusing the same password across multiple sites violates the principle of credential isolation; if one site suffers a data breach, attackers can use the stolen password to compromise all other accounts where it is reused. This practice is tempting because it simplifies memorisation and login speed, and it would be acceptable only if every site used a separate, unique password—never the same one.
- ✗
Using your pet's name as a password
Why it's wrong here
Personal information is easily guessed.
