Set up Multi factor authentication in Microsoft 365 by Security Defaults
In this article, we will explore how we can enable multi-factor authentication in Microsoft 365 (also known as Office 365) by means of Security Defaults
Background and Introduction
Multi factor authentication (MFA) is a much-needed security feature for any cloud tenant or cloud-based applications. Relying singularly and entirely on passwords leaves your accounts susceptible to threats. Passwords can be weakly selected words, or commonly used across websites, etc.
MFA provides that added layer of security towards authentication. Multi-factor authentication is a simple process where users are authenticated by an additional step of verification such as a face unlock via your connected phone, or an SMS on your mobile number. A combination of strong password and MFA verification provides an excellent security to your online accesses to cloud applications and services.
MFA can be controlled or configured by any of the below means. The prerequisite however exists that the account performing the steps must be a “Global Admin” (“SharePoint Admin” in case of per person MFA). The means are –
- Security Defaults
Enable MFA via Security Defaults
Step 1. Sign into Microsoft 365 Admin Center from this URL https://admin.microsoft.com/
Step 2: Click on Azure Active Directory under Admin Centres
Step 3: Click on Azure Active Directory from the Azure Portal you are redirected to.
Step 4: Click on Properties
Step 5: Click on Manage Security Defaults
Step 6: Enable the Security Defaults – Select Yes. Click on Save.
This will enable MFA for your tenant. In the next articles, we will see the other means of activating MFA.
