Protection of digital privacy in a dental office can best be ensured by which of the following?

  1. Giving passwords only to trusted employees
  2. Multi-factor authentication for system access
  3. Using a single shared login for the office computer
  4. Changing passwords every 60 days
Show answer and explanation

Correct answer: B. Multi-factor authentication for system access

  • A. Limiting password access reduces risk but does not prevent breaches if that password is compromised.
  • B. Correct. Multi-factor authentication (MFA) requires multiple verification steps to access a system, significantly reducing the risk of unauthorized access even if a password is compromised. This is the most effective single security measure listed.
  • C. Shared logins undermine accountability and are specifically discouraged under HIPAA Security Rule requirements.
  • D. Periodic password changes are recommended but are less robust than multi-factor authentication alone.
