How to Disable Two-Factor Authentication in Office 365

As the founder of SupportFly, I frequently encounter clients who need help managing their Office 365 security settings. While Two-Factor Authentication (2FA) is a great way to secure accounts, there are situations where you may want to disable it—whether for troubleshooting or adjusting security protocols. In this post, I’ll guide you through the process of disabling 2FA in Office 365.

Why Disable Two-Factor Authentication?

It’s important to understand that 2FA provides an extra layer of protection by requiring a password and an additional verification step, like a text message code. This makes it much harder for unauthorized users to access your account, even if they have your password.

However, there are valid reasons to disable it:

• Convenience: If 2FA is causing login delays or issues.
• Troubleshooting: If users are experiencing problems receiving authentication codes.
• Alternative Security Measures: You may have other layers of security in place.

Let’s walk through how to disable 2FA in Office 365.

Step-by-Step Guide to Disable Two-Factor Authentication in Office 365

1. Go to the Microsoft 365 Admin Center and log in with an account that has Global Administrator permissions.
2. Navigate to Users > Active Users.
3. Click on Multi-factor Authentication.

4. A page will display a list of users and their MFA status. Note that this page does not show whether the user has completed MFA or which method they have enabled.

5. To disable MFA for a specific user, select the user from the list.

6. In the right-hand column, under Quick Steps, you'll see options to enable, disable, or configure MFA settings for the user.

7. Click Disable and confirm to turn off MFA for the selected user.

In the Service Settings tab, you can adjust additional MFA configurations, such as:

• Adding trusted IP subnets where users are exempt from MFA.
• Enabling/disabling specific MFA methods.
• Allowing users to remember MFA on trusted devices for a set period (from 1 to 365 days).

Final Thoughts

While disabling Two-Factor Authentication can simplify the user experience, always consider the security implications. If you must disable 2FA, ensure you have other strong security measures in place, such as complex passwords and restricted access controls.
