Whenever you access or make a change to personal account information or you add a new security proof to your account, a special code is generated and sent to an email address or mobile phone number that is associated with your account as a “security proof.” Generally, it only takes a few moments to receive the code. Find out what to do if you don’t receive this code.
Didn’t receive a code
If you don’t promptly receive the code to confirm your account ownership, the delay could be due to issues with your wireless carrier or your Internet service provider (ISP). Try waiting for a bit longer. If you still do not receive the code, we recommend using a different security proof that you already have on your account. For more information about how to switch to another existing security proof, see Add and update security proofs for your Microsoft account.
Added a new security proof but didn’t receive the code
When you add a new security proof, a code is sent to that proof, and then you are prompted to enter it to confirm that the new security proof works. Typically, it only takes a few moments to receive your code, but the exact timing depends on your wireless carrier or Internet service provider. In this case, you may need wait a little longer.
Note If you request a new code, the previous code that you requested becomes non-valid. If you enter the previous code, you will get an error that states that the code is not valid.
