Connect Microsoft365 with Third-Party Apps

Enabling Two-Factor Authentication (2FA)

Before we proceed with enabling App Passwords, it's important to enable two-factor authentication on your Microsoft 365 account. Here's how you can do it:



Option 1

  • Go to the Microsoft 365 admin center (https://admin.microsoft.com/) and log in as an administrator.
  • Click on "Users" from the left-hand menu and select "Active users".
  • Select the user for whom you want to enable 2FA, and click on "Enable" under "More settings" on the right-hand side of the page.
  • Follow the prompts to complete the setup process. You can choose to receive verification codes via SMS, phone call, or through the Microsoft Authenticator app.

Option 2

  • Sign in to your Microsoft 365 email address and password.
  • After you're signed in, go to the MFA page
  • Select the user(s) and click on “Enable”, and “Enable Multi-Factor Auth”
  • Sign out and sign in back to your Microsoft 365 account
  • Set up MFA with either your phone number (from I want to set up a different method) or Microsoft Authenticator App


Enabling App Passwords

Now that you have enabled 2FA on your account, you can proceed to generate an App Password for applications that don't support 2FA. Here's how you can do it:


  • Go to your Microsoft365 My Account page and Security Info
  • Click on “Add Sign-in Method” and choose “App Password”
  • Enter a Name, this could be anything
  • Your App Password will be generated
