What is multifactor authentication?
MFA adds another way to verify a sign-in beyond the password.
Understand the idea
Multifactor authentication combines different types of evidence, such as a password and an approved authenticator or security key. The available methods depend on the service and configuration.
Review important accounts
Discuss business email, administrative accounts, remote access, financial services, and other sensitive applications. Confirm supported methods and account recovery options before changing policies.
Plan the rollout
Users need clear enrollment instructions, approved devices or methods, and a recovery process. Coordinate changes so that business work can continue.
Recognize the limits
MFA reduces some account risks, but it does not replace secure devices, careful approval of prompts, access management, and a broader security plan.
Keep the process documented
Record the approved method, account owner, and support process. Do not store recovery information in an ordinary website inquiry or email message.
