Multifactor authentication (MFA) is a security feature that adds an extra layer of protection to your account by requiring users to provide more than one method of authentication before gaining access. With the increasing number of security breaches and cyberattacks, MFA has become an essential security measure for any organization that wants to safeguard its data and prevent unauthorized access. Microsoft 365, formerly known as Office 365, offers multifactor authentication as a standard feature, and in this article, we will guide you through the process of setting up MFA in Microsoft 365.
Step 1: Sign in to the Microsoft 365 admin center To set up MFA, you need to have admin rights to the Microsoft 365 account. Sign in to the Microsoft 365 admin center with your admin credentials. Once you are signed in, select the “Users” option from the navigation menu.
Step 2: Select the users who need MFA Select the users who you want to enable MFA for by checking the box next to their name. You can select multiple users at once by holding down the “Ctrl” key on your keyboard while selecting the users.
Step 3: Enable MFA for the selected users Once you have selected the users who need MFA, click on the “Enable” button under the “Multifactor authentication” option in the toolbar. This will bring up a dialog box with the list of users you have selected.
Step 4: Choose the MFA settings In the dialog box, you can choose the MFA settings for the selected users. There are three options available:
- Disabled: This option will turn off MFA for the selected users.
- Enforced: This option will require the selected users to set up MFA on their next sign-in attempt.
- Enabled: This option will immediately enable MFA for the selected users.
Choose the appropriate option for your organization and click “Enable multi-factor auth” to save the changes.
Step 5: Configure the MFA settings Once you have enabled MFA for the selected users, you can configure the MFA settings by clicking on the “Service settings” option in the toolbar. This will open the MFA service settings page.
On this page, you can configure the following settings:
- User settings: This setting allows you to configure the default MFA settings for all users in your organization.
- App passwords: This setting allows you to create and manage app passwords for users who need to access non-browser-based apps that don’t support MFA.
- Trusted IPs: This setting allows you to specify the IP addresses or ranges that are considered safe and exempt from MFA requirements.
- Verification options: This setting allows you to choose the MFA verification options that are available to your users, such as text message, phone call, or mobile app notification.
- Fraud alerts: This setting allows you to configure the fraud alert notifications that are sent to users when suspicious activity is detected on their account.
Step 6: Require MFA for all users To further enhance the security of your organization, you can require MFA for all users by clicking on the “Service settings” option in the toolbar and selecting the “Azure AD” option. On the Azure AD page, select the “Security” option from the navigation menu and then select “Conditional Access.”
On the Conditional Access page, click on the “New policy” button to create a new policy. In the “Assignments” section, select “Users and groups” and choose “All users.” In the “Access controls” section, select “Grant” and then select “Require multi-factor authentication.” Finally, give the policy a name and click “Create” to save the changes.
