Hi! My name is Aj and Im an Independent Advisor here to help!
Try logging in using inprivate/incognito mode on a browser or use a different device.
If none of that works, on the sign-in screen, when prompted to verify identity, pick "I dont have any of these" and follow the prompts to replace your security info. But note that if successful, there will bea 30-day waiting period during which some features may be restricted.
Last resort will be the account recovery form at account.live.com/acsr and fill it out as much as information as you can. The more accurate detail you provide, the better your chance. There's no guarantee, but it's your only option outside of codes.
