Multifactor authentication (MFA) requires users to provide two or more verification factors to gain access to a resource such as an application, online account, or a VPN. By implementing MFA, the cloud service provider would add an additional layer of security to the administrative login process, which reduces the likelihood of unauthorized access due to compromised passwords. Single sign-on (SSO) streamlines user access but does not inherently increase security without additional measures like MFA. Role-based access controls are important for defining what resources a user can access once authenticated but don't address the authentication strength. Certificate management generally pertains to the management of digital certificates, which could be a part of MFA but, on its own, is not necessarily a method for strengthening login processes.
