Hello @Maria Alice Rodrigues,
Thank you for posting your query on Microsoft Q&A.
Currently, Microsoft Q&A provides support in English. I used a translator to understand your issue.
Based on your description, it seems that after formatting your personal computer, you are prompted to log in with your Microsoft account. However, after entering the correct username and password, you encounter another password prompt. According to the screenshot you shared, it appears that the second prompt is asking for your current Windows password. This second password prompt is to verify your identity and is not related to your Microsoft account password. You should enter the Windows password that was set up on that PC. After completing this step, you can restart your PC and then log in with your Microsoft account credentials.
In summary, the first prompt requests your Microsoft account username and password, while the second prompt asks for your local Windows account password to confirm your identity.
I hope this information is helpful. Please feel free to reach out if you have any further questions.
