Which of the following is an OATH-based standard to generate event-based, one-time password tokens?

Answer options

• A. HOTP
• B. SOTP
• C. TOTP
• D. OLTP

Correct answer: A

Explanation

The correct answer is A, HOTP, which is specifically designed as an event-based one-time password algorithm under OATH standards.
