Hello, thank you for reaching out to Microsoft Q&A.
Sometimes waiting a day can resolve the issue. Don't make repeated attempts, as this will reset the time lock.
After 24 hours, open an incognito tab on any web browser and sign in with your Microsoft account:
https://account.live.com/ResetPassword.aspx
Before you look to reset your password, double-check that you are using the correct email address when logging in.
See if you can successfully reset your password.
If it still fails and you have access to your Microsoft account still, we can add authentication as the verification method and use it to verify your identity during the password reset process.
Let me know if you still need more help.
