You didn't receive a security code
Whenever you access, change personal information or add new contact information to your Microsoft account, a security code is generated and sent to an email address or mobile phone number in your account security information. You're then prompted to enter that code to confirm the change. Generally, it only takes a few moments to receive the code.
Reasons you might not get the security code and things to try
Your security information is outdated or inaccessible
You might not receive the code if your security information is outdated and you can't access it anymore (for example, you changed email addresses or phone numbers).
To resolve this issue, update your security information. See Update all your Microsoft account security information.
Wireless carrier or ISP delay
If you don't promptly receive the security code, the delay could be due to issues with your wireless carrier or your Internet service provider (ISP). Here are some things you can try:
- If you used an email address to get the code, check your junk mail folder.
- Just wait a bit longer. Some carriers process requests more slowly than others.
- If you still don’t get the code, use a different security contact method that’s associated with your account to get the code.
Note If you request a new code, the previous code that you requested becomes invalid. If you enter the previous code, you'll get an error message that states the code isn't valid.
