Hi @Guillermo Camacho

Welcome to Microsoft Q&A platform and thanks for posting your question here.

Based on the error message you provided, "AADSTS900561: The endpoint only accepts POST requests. Received a GET request." indicates an issue with the authentication endpoint. It's crucial to follow the correct protocol for communication.

To resolve that you may need to add https://login.microsoftonline.com and https://autologon.microsoftazuread-sso.com/ to your list of trusted sites in your browser.

If it is chrome you can follow the steps:

1. At the top right, click "More" and then "Settings."
2. Click "Privacy and security" and then "Site Settings."
3. Click "Additional content settings" and then "Insecure content."
4. Next to "Not allowed to show insecure content," click "Add."

From here you just need to add these two sites:

• login.microsoftonline.com
• https://autologon.microsoftazuread-sso.com

Once you have added these sites to your list of trusted sites, try accessing the Microsoft login page again and see if the issue is resolved. If you are still having trouble, you may need to contact Microsoft support for further assistance.

Regarding your issue with 2-step verification, if you have lost access to the phone number associated with your account, we recommend that you contact your organization's IT support team for assistance. They may be able to help you regain access to your account by resetting your password or verifying your identity through other means.
