Hello, thank you for reaching out to Microsoft Q&A.
I understand that you're having trouble signing in with your Microsoft account to install the Office applications on your device.
- Do you have any additional verification methods, such as a recovery email address, to confirm your identity?
- What happens if you request a verification code to your phone number? Do you get any error messages, or is the code not received on your phone?
Did you check if your phone isn't blocking texts from unknown numbers?
Check your blocked sender lists and clear them.
Alternatively, you can try a different web browser or use incognito mode and attempt to request the verification code on your Phone number. Sometimes, connecting your Mobile data network and requesting the verification code might also work.
For reference, see the Troubleshooting verification code issues article.
Let me know if you still need more help.
