Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

A one-time password (OTP) is a password that is valid for only one login session or transaction. OTPs avoid a number of shortcomings that are associated with static passwords. The most important shortcoming that is addressed by OTPs is that, in contrast to static passwords, they are not vulnerable to replay attacks. This means that a potential intruder who manages to record an OTP that was already used to log into a service or to conduct a transaction will not be able to abuse it, since it will be no longer valid.

Symmetric encryption uses a single shared key, while asymmetric uses the public/private pair.
