A system employs two‑factor authentication. The first factor is a password of length 8, where each character can be any of the 62 alphanumeric symbols (26 uppercase, 26 lowercase, 10 digits). The second factor is a 6‑digit one‑time password (OTP) where each digit is 0-9. An attacker can test 1,000 password guesses per second and 500 OTP guesses per second, independently. Assuming the attacker must guess both factors correctly in the same session, estimate the expected time (in years) required to compromise the account.
