Using a rainbow table to crack a password requires three steps: Creation of the table, comparing the table to known hash values, and decrypting the password.
False

OAuth
What type of one-time password (OTP) changes after a set time period?

True
What is the center of the weakness of passwords?
human memory
What variation of a dictionary attack involves a dictionary attack combined with a brute force attack, and will slightly alter dictionary words by adding numbers to the end of the password, spelling words backward, slightly misspelling words, or including special characters?
hybrid
What type of attack involves an attacker stealing a file containing password digests and comparing the digests with digests created by the attacker?
