WHAT IS 2FA?
Two-factor authentication is a security protocol that requires two different forms of identification to verify you are who you say you are before allowing access to an account. For example, in addition to entering your User ID and password (one form of identification), you might also be required to submit a verification code sent to your phone. This is just one method of 2FA, but there are many.
WHY IS 2FA IMPORTANT?
Simply put, two-factor authentication makes it harder for outside attackers to access sensitive or private information such as bank accounts or customer data. An Office 365 account that provides access to email, documents, financial statements, customer data, and a multitude of
other information is exactly the kind of account that’s most valuable to attackers. Think about a time where you’ve had to request a password change for your bank account – where does your bank send the reset link? To your email account! If hackers have access to your email account, they’re able to see everything you see, putting your sensitive data at risk.
In addition, as phishing threats continue to rise, so does the risk of your user ID and password falling into the wrong hands. However, if 2FA is enabled, your User ID and password aren’t enough to allow the attacker into your account, and your information will be better protected.
HOW DOES 2FA WORK?
2FA can be enabled through a variety of methods and will depend on how you choose to set it up. For Microsoft 365, you can choose to verify with a unique code sent to your phone, a phone call or by using the Microsoft Authenticator app. Once you set up your method and identify your computer and other devices as “trusted,” you will only be prompted to enter a new security code any time you log in to a device that isn’t trusted. That means you won’t have to authenticate over and over again on devices you use regularly.
We also recommend setting up an additional verification method for Office 365 in case of a lost or stolen phone or mobile device. This enables a user to make use of the “sign in another way” link to access the account. If an alternative verification method has not been set, the user will need to work with the help desk to access and update the account.
Protecting business assets and customer data should be a top priority for any company and enabling two-factor authentication for Office 365 is a simple first step to getting it done. Contact us today to get started.
By setting up MFA, you add an extra layer of security to your Microsoft 365 account sign-in. For example, you first enter your password and, when prompted, you also type a dynamically generated verification code provided by an authenticator app or sent to your phone.
Sign in to Microsoft 365 with your work or school account with your password like you normally do. After you choose Sign in, you'll be prompted for more information.

The default authentication method is to use the free Microsoft Authenticator app. If you have it installed on your mobile device, select Next and follow the prompts to add this account. If you don't have it installed there is a link provided to download it.
If you would rather use SMS messages sent to your phone instead, select I want to set up a different method. Microsoft 365 will ask for your mobile number, then send you an SMS message containing a 6-digit code to verify your device.
Tip: For a faster, and more secure, experience we recommend using an authenticator app rather than SMS verification.
Once you complete the instructions to specify your additional verification method, the next time you sign in to Microsoft 365, you'll be prompted to provide the additional verification information or action, such as typing the verification code provided by your authenticator app or sent to you by text message.
