How to Fix Microsoft 365 Security Info Redirect and Authentication Setup Problems

Product: Microsoft 365
Device & OS: not provided
Scenario: Attempting to access Security Info or configure phone authentication methods for a work or school account.
Observed behavior: The account redirects to an automatic verification-code page, indicating a blocked or incorrectly configured authentication method that prevents the user from completing the setup.

Before you start

Confirm whether you are using a Microsoft 365 work, school, or personal account, as troubleshooting steps and admin access requirements differ significantly for each type.

Solution 1Recommended

Contact Your Administrator to Reset Authentication Methods

For work or school accounts, your organization's IT administrator has the necessary permissions to clear blocked sessions and reset your authentication options.

When an authentication method is incorrectly configured or flagged by security policies, you may get stuck in a redirect loop. End users cannot bypass this manually; an admin must intervene via the Microsoft Entra admin center.

Identify your Microsoft 365 administrator

Determine who manages your organization's IT services. This is typically your IT helpdesk, network administrator, or the person who issued your login credentials.

Request an authentication method reset

Ask your administrator to navigate to your user profile in the Microsoft Entra admin center and reset your authentication methods, specifically clearing the conflicting phone authentication settings.

Reconfigure your Security Info

Once the administrator confirms the reset, sign in to your Microsoft 365 account again, navigate to the Security Info page, and follow the prompts to set up your phone authentication from scratch.

Finding Your Admin: If you do not know who your administrator is, check your organization's internal directory or contact your HR department for guidance on IT support.

Solution 2

Contact Microsoft Business Support (For Sole Administrators)

If you are the only global administrator for your Microsoft 365 tenant and are locked out by the redirect loop, you must contact Microsoft directly to regain access.

Frequently Asked Questions

Why does my Microsoft 365 account keep redirecting me to a verification page?

This usually happens when your multi-factor authentication (MFA) method is incorrectly configured, blocked by a security policy, or out of sync. The system attempts to verify your identity but fails to load the proper setup interface, resulting in a redirect loop.

How do I find out who my Microsoft 365 administrator is?

Your administrator is typically the person who gave you your Microsoft 365 user account and password. In a work environment, this is usually your IT department or Help Desk. In a school environment, it is likely your university's technical support team.

Can I reset my own Microsoft 365 authentication methods?

If you are an end user and are locked in a redirect loop, you cannot reset the methods yourself because you cannot access the Security Info page. An administrator must clear the settings for you from the backend.

What if I am the only administrator and I get locked out?

If you are the sole global admin and cannot bypass the verification redirect, you must contact Microsoft Data Protection or Business Support by phone. They have specialized procedures to verify your identity and restore access to your tenant.
