Multi-factor authentication (MFA) is a multi-step account login process that requires users to enter more information than just a password. For example, along with the password, users might be asked to enter a code sent to their email, answer a secret question, or scan a fingerprint.

Authentication

Authentication systems verify identities. These systems could consist of usernames and passwords, PINs, credit card numbers or fingerprints. When you enter your identifiable information, the interface checks it against a database. If your inputted information matches the system records, the IAM system recognizes you as an accepted user. Authentication prevents restricted users or people outside your organization from accessing private company interfaces.

Depending on company preferences, identity and access management systems can use various technological components. For example, an IAM system could feature elements like:

• Single sign-on (SSO) systems: This authentication method verifies user identity with a single set of credentials, such as one username and password combination.
• Two-factor authentication: This method adds another layer of identification for extra security. For example, a user might have to answer a personal question or provide a fingerprint after they submit their login credentials.
