Multi-factor authentication is a security enhancement used to nearly eliminate account breaches that can compromise organizations by requiring a two-step verification method. A 2019 ZDNet article said enabling MFA in Office 365 or Google will eliminate 99.9% of account breaches. This video demonstrates four different end-user MFA experiences.
We’ll look at two within the Microsoft Authenticator Application, as well as a text message and phone call approval.
On our cell phone, we’ll use the Microsoft Authenticator app to approve a two-factor authentication request—this looks almost identical on both Apple and Android phones and is the quickest way to do MFA.
We’ll start by going to the Office 365 portal at portal.office.com. Enter our username and password. You’ll see we have received a two-factor authentication request directly to our phone. I select Approve in the application and then click Yes to stay logged in. And now we are fully logged in.
Here we will log in to Office 365 and use a rotating PIN within the Microsoft Authenticator app to approve a two-factor authentication. Again, we go to portal.office.com and enter the username and password. Now we go directly into our Authenticator app. You’ll see here there’s a rotating PIN based on time—enter in the PIN and click on verify. Click on Yes to stay signed in. Now you can see we’re fully logged in.
Next, we’ll use a text message for two-factor authentication. I’ll again go to portal.office.com and enter my username and password and press Sign In. After a few seconds I will receive a text message. Open it up and there will be a 6-digit PIN code. Enter that PIN into the portal and select Verify. Click on Yes to stay logged in. Now you can see we’re fully logged onto Office 365.
Finally, I’ll use a phone call to approve two-factor authentication. Once again, we go to portal.office.com and enter the username and password. Now we wait for our phone call.
We press the # key.
Click on Yes to stay signed in and we are fully logged into Office 365.
