Multi-factor authentication (MFA) strengthens account security by requiring users to provide two or more methods of verification during sign-in, such as a password and a verification code sent to a mobile device. This reduces the risk of unauthorized access even if one credential is compromised. Conditional access policies control access based on conditions like user location or device compliance but do not require additional verification methods. Single sign-on (SSO) allows users to access multiple applications with one set of credentials, improving convenience but not necessarily enhancing security through multiple identification methods. Self-service password reset (SSPR) enables users to reset their own passwords without administrator assistance but does not involve providing multiple identification methods during sign-in.
