Two-step verification is a method to confirm your identity by using something that only you know, for example, a password, and adding one additional step before being granted access. Sometimes two-step authentication, which is a subset of multi-factor authentication, and two-step verification are mixed up (and cause confusion). However, if the information in your Office 365 documents and your Office 365 email account is very important to you, you can also configure MFA for Office 365. MFA is highly recommended for internet banking.

Inheritance – something you are (biometric data such as fingerprint, your eye, your face, etc.)īy using MFA, a system can ensure that it is the real user who is entering the username and password and not a person with bad intentions who has compromised a user account by stealing the username and password.

Possession – something you have (a cell phone, USB key, smart card, token, etc.).

Knowledge – something you know (a password, pin code, etc.).

Generally, the types of information used by MFA can be classified into tree types: Second, they have to confirm their identity by providing additional information that can only be accessed by them, for example, a confirmation call, SMS code, USB key, fingerprint, face image, etc. With two-factor authentication, first, a user has to enter information that only they know. Multi-factor authentication (MFA) is a method to confirm the identity of a user by requiring multiple credentials before authorization and before providing access to a website, application or other resources. This blog post explains what multi-factor authentication is, and how to use it in Office 365 and Office 365 app passwords. Some companies use multi-factor authentication by default in accordance with their security policy. If a single password meeting Office 365 password requirements is not enough to protect your account or accounts of users in your organization, consider using multi-factor authentication, which is supported by Microsoft Office 365. Add to that software vulnerabilities and user resilience to social engineering tricks and phishing attacks.

However, the security of an account is only as strong as its password.

Using a username and a password as login is a classic method of authentication.
