MFA vs SSO

MFA hardens proof of identity. SSO reduces login friction across apps after that proof succeeds.

MFA

Multi-factor authentication, or MFA, is a security process that verifies a user's identity using two or more distinct pieces of evidence. These factors typically fall into three categories: something the user knows (like a password), something the user possesses (like a phone or.

MFA requires multiple proofs of identity to grant access, significantly boosting security beyond just passwords.

SSO

Single sign-on SSO is an authentication scheme that allows a user to log in with a single set of credentials to access multiple independent software systems. Instead of remembering and entering different usernames and passwords for each application, users are granted access to.

SSO lets users access multiple applications with one login, simplifying access and improving efficiency.
