For the following scenario, indicate whether the action is a good practice or bad practice for safeguarding your personally identifiable information. Sierra uses a long pass phrase such as "A stitch in time saves 9" with special characters between the words for her bank account password. Question 21 options: A) Good practice B) Bad practice

A) Good practice

Explanation:

Passwords, sometimes called a passcode, are memorized secrets, typically a string of characters, used to confirm the identity of a user. Using a long pass phrase is much more better than a short one.

Suppose, you select a 2-character numeric password. Then you would have 10 possible selections for each character, giving 10 x 10 = 100 possible combinations. With a little patience, a human cracker would be successful within a very short time: just 50 tries, on average.

But adding alphabetic and numeric characters to a 3 character password, the hacker must try 62 x 62 x 62 = 238328 different passwords just to hack and get your personal information. For an 8 character passwords, it will take weeks.

Hence, the longer the password the better. This is why it is a good practice for Sierra to use a long passphrase.
