What is MFA?
Multifactor authentication (MFA) is defined as a security process that requires more than one method of authentication from independent sources to verify the user’s identity.
In other words, a person wishing to use the system is given access only after providing two or more pieces of information which uniquely identifies that person.
When should it be used?
MFA should be used to add an additional layer of security around sites containing sensitive information, or whenever enhanced security is desirable. MFA makes it more difficult for unauthorized people to log in as the account holder.
According to the National Institute of Standards and Technology (NIST) MFA should be used whenever possible, especially when it comes to your most sensitive data—like your primary email, financial accounts, and health records.
Some organizations will require you to use MFA; with others it is optional. If you have the option to enable it, you should take the initiative to do so to protect your data and your identity.
