Fix Microsoft MFA Setup Redirecting to Security Information
Question details
Users experience an endless redirect loop to the Security Information page when attempting to set up Microsoft multifactor authentication (MFA).
- Product
- Microsoft 365
- Device & OS
- Windows
- Scenario
- Setting up Microsoft multifactor authentication for a Microsoft Office account.
- Observed behavior
- The authentication setup fails to complete and continuously redirects the user back to the Security Information portal.
Ensure you have your Microsoft 365 administrator contact details handy, as you may need admin privileges to check tenant-wide authentication settings.
Enable Modern Authentication and Update Outlook
Resolve the redirect loop by verifying that Modern Authentication is active for your Microsoft 365 tenant and ensuring you use a supported Outlook client.
The redirect issue typically occurs because the email client or the organization's Microsoft 365 tenant is not configured to handle Modern Authentication, which is required for multifactor authentication flows.
Ensure you are using a supported client, such as Outlook 2016, Outlook 2019, or Microsoft 365 Apps. Older versions may not support Modern Authentication natively.
Contact your IT administrator and ask them to navigate to the Microsoft 365 admin center to confirm that Modern Authentication is enabled for the entire organization's tenant.
Ensure that Modern Authentication is enabled for Microsoft Office on your Windows device. If it is disabled via the Windows Registry or Group Policy, the MFA prompt cannot complete.
If the issue persists after updating your client and confirming tenant settings, ask your administrator to open a support ticket or request assistance through the Microsoft Tech Community.

Frequently Asked Questions
Why does my Microsoft MFA setup keep looping back to the Security Info page?
This typically happens if Modern Authentication is not enabled on your Microsoft 365 tenant or your local device, or if you are using an outdated email client that does not support the latest security protocols.
What versions of Outlook support Modern Authentication?
Outlook 2016, Outlook 2019, Outlook 2021, and Outlook for Microsoft 365 natively support Modern Authentication. Older versions like Outlook 2013 may require registry updates.
Can I bypass the Microsoft MFA setup if it keeps failing?
Usually, you cannot bypass MFA if your organization's IT administrator has enforced it via Conditional Access policies. You must resolve the underlying Modern Authentication issue or contact your admin for a temporary exclusion.
