Problem 1 – No verification code arriving
- Check the email address shown on the screen very carefully (spelling and domain such as .com vs .co.uk). If it is not exactly your child’s address, you will never receive the code. In that case, use account recovery.
- If the address is correct but no code arrives, this is treated as a verification-code delivery issue. In this situation Microsoft recommends:
- Try a different verification method on the sign-in screen if one is offered (alternate email, phone, Authenticator, etc.).
- If no other method works and you still cannot receive codes, use the account recovery form for that Microsoft account: see “Help with the Microsoft account recovery form” in the references.
- If the account is blocked or repeatedly failing, wait and avoid many repeated attempts, then try again or use the Sign-in helper tool to diagnose the sign-in problem.
If none of the above works, use the Sign-in helper tool to identify the issue and then contact Microsoft Support from another account (such as a parent account) using the “Contact Microsoft Support” flow described in the references.
Problem 2 – Why email codes and how to use PIN/no password
The account is being challenged with a verification code because Microsoft detected a sign-in that requires extra verification (for example, unusual activity, new device, or policy). This is expected behavior for Microsoft accounts, including child accounts.
Once access to the account is restored and the child can sign in to Windows again, a PIN or passwordless sign-in can be configured:
- Sign in to Windows with the child’s Microsoft account.
- Set up a PIN or passwordless method on that device (for example, Windows Hello PIN, fingerprint, or using Microsoft Authenticator) following the “Go passwordless” guidance. Passwordless sign-in replaces the need to enter the account password each time.
Problem 3 – Getting additional help / live support
If self-help and the Sign-in helper are not resolving the issue:
- Use the Sign-in helper tool for the child’s account issue: it can detect most sign-in problems and route to available support options.
- If still stuck, sign in with any working Microsoft account (for example, the parent’s account) and go to Contact Microsoft Support:
- Enter a short description such as “Child account cannot receive verification code / cannot sign in”.
- Select Get Help.
- If automated suggestions do not solve it, choose Contact Support to see available options (such as chat with a support agent in the browser).
Support agents cannot send verification codes or directly change account security info, but they can guide through the correct recovery and troubleshooting steps.
