Minecraft will not let me sign into my Microsoft account

Since sign-in works on the Nintendo Switch but fails on the iPad after the Microsoft sign-in window closes, focus on Microsoft account sign-in checks on that device and connection.

Try these steps in order:

1. Use the Microsoft account Sign-in Helper first: Sign-in helper. It checks the email address or phone number used for sign-in and identifies account problems.
2. If the account signs in elsewhere but keeps failing on the iPad, avoid private browsing or any in-app browser mode that behaves like Incognito/InPrivate.
3. Temporarily disable ad blockers, privacy extensions, content blockers, or network-level blocking features.
4. Turn off any VPN or proxy on the iPad, then try again on the normal internet connection.
5. Make sure cookies and JavaScript are enabled in the browser flow used for sign-in.
6. Try a different network. If currently on school, work, hotel, or other shared Wi-Fi, switch to a personal connection.
7. Turn off Wi‑Fi on the iPad and try the sign-in flow using a mobile phone hotspot or cellular-backed connection.
8. Clear browser cache and cookies, then try again.
9. Update the browser and restart the iPad.

If the issue is a repeated security-check failure during sign-in, these are the documented fixes for that Microsoft account error path.

If the account itself is not being recognized, or the password suddenly stopped working, use the Sign-in Helper again. If the username is reported as not found, the documented recovery path is also to use the Sign-in Helper. If the account has been inactive for more than two years, it may have been deleted.

If none of the above works, use Contact Microsoft Support. Support can route the case, but support agents cannot send password reset links or change account details.
