Hi Shiv Shankar1,
thank you for posting on the Microsoft Community Forums.
If you are unable to receive the security code on your mobile number and consequently cannot log into your laptop, here are a few steps you can take to resolve the issue:
- Verify Mobile Number: Make sure the mobile number you have registered with your school account is correct. There could be a typo or an old number that you no longer use.
- Check for Network Issues: Ensure that your mobile phone has a good network connection to receive SMS messages. Sometimes, network issues can delay or prevent the delivery of SMS codes.
- Resend Code: Most systems have an option to resend the security code. Wait a few minutes and then request the code again.
- Contact Your School's IT Department: In case you are still unable to log in, you might need to contact your school's IT department. They may be able to help you bypass the security code step or provide an alternative method for account verification.
Hope it helps.
Kind regards,
Lei
