How to Disable MFA for an Entire Microsoft Entra Tenant
Product
Microsoft Entra ID
Device & OS
not provided
Scenario
Performing a temporary migration or system setup that requires tenant-wide MFA to be temporarily turned off.
Observed behavior
Security defaults enforce MFA for all users, blocking automated migration scripts or legacy authentication setups.
Before you start

Ensure you have global administrator privileges in the Microsoft Entra admin center. Disabling tenant-wide MFA significantly reduces security, so plan to re-enable it immediately after your migration is complete.

Solution 1Recommended

Disable Security Defaults in Microsoft Entra Admin Center

This solution turns off the baseline security defaults, effectively disabling tenant-wide MFA. Use this only temporarily during migrations.

Microsoft Entra ID enforces multifactor authentication for all users by default to protect the tenant. Disabling this feature reduces security and should be limited to necessary situations, such as large-scale automated migrations.

1
Sign in as Administrator

Log in to the Microsoft Entra admin center using an account with Global Administrator permissions.

2
Navigate to Tenant Properties

Go to 'Microsoft Entra ID' in the left navigation menu, click on 'Overview', and then select 'Properties'.

3
Access Security Defaults

Scroll to the bottom of the Properties page and click the 'Manage security defaults' link.

4
Disable the Setting

In the 'Security defaults' side panel, change the setting to 'Disabled'. Select a reason for disabling from the dropdown prompt and click 'Save'.

Security Best Practice: Remember to re-enable security defaults immediately after your migration is complete. If you only need to bypass MFA for specific accounts, consider using Conditional Access policies instead of disabling tenant-wide settings.

Frequently Asked Questions

Is it safe to disable MFA for the entire tenant?

Disabling MFA tenant-wide is not recommended for standard operations as it leaves your organization vulnerable to credential attacks. It should only be done temporarily during specific migrations and re-enabled as soon as possible.

Can I disable MFA for specific users instead of the whole tenant?

Yes, if you have Microsoft Entra ID P1 or P2 licenses, it is highly recommended to use Conditional Access policies to exclude specific users or groups from MFA rather than disabling security defaults entirely.

Why is the 'Manage security defaults' option grayed out?

The option might be unavailable if you do not have the required Global Administrator permissions, or if your tenant has Conditional Access policies actively enabled that conflict with security defaults.

Do I need a premium license to disable security defaults?

No, security defaults are available and can be managed in the free tier of Microsoft Entra ID. However, advanced granular MFA controls (like excluding specific accounts) require a premium license.
