Users currently access SaaS email with five-character passwords that use only letters and numbers. An administrator needs to make access more secure without changing the password policy. Which of the following will provide a more secure way of accessing email at the lowest cost?
To provide a more secure way of accessing email without changing the password policy, enabling Multi-Factor Authentication (MFA) with a one-time password is the best solution. MFA adds an extra layer of security by requiring users to provide an additional form of verification beyond their simple passwords. This significantly reduces the risk of unauthorized access and can be implemented at a relatively low cost compared to other security measures like changing the service provider or instituting certificate-based authentication.
B. Enable MFA with a one-time password: Multi-factor authentication (MFA) adds an additional layer of security by requiring users to provide a one-time password (OTP) in addition to their existing password. This significantly increases security at a relatively low cost.
