Two-Factor Authentication (2FA) is one of the simplest yet most powerful tools to protect your accounts from unauthorized access
Here’s a quick and clear guide to implementing 2FA for a single user in Microsoft 365.
Step 1: Sign in to Microsoft 365 Admin Center
- Go to: https://admin.microsoft.com
- Use your global admin credentials.
Step 2: Access the Multi-Factor Authentication Settings
- In the Admin Center, go to Users > Active users.
- Click Multi-factor authentication (top menu).
Step 3: Search for the Specific Users
Use the search bar to find the user you want to enable 2FA for.
Step 4: Enable 2FA
- Select the checkbox next to the user’s name.
- On the right panel, click Enable.
- Confirm by clicking Enable Multi-Factor Auth in the popup.
The user’s 2FA is now enabled but not yet enforced until setup is complete. Enforcing 2FA is highly recommended to ensure Security.
Step 5: User Sets Up 2FA at Next Login
The next time the user logs in, they will be prompted to configure 2FA. Options include:
- Microsoft Authenticator app (Recommended)
- Phone call
- Text message
Even enabling 2FA for just one user can dramatically reduce risk, especially for accounts with access to sensitive data or administrative privileges
