Hi there, Thanks for reaching out. If you're having trouble with authenticating one particular platform account, we recommend you try logging in using that one first. In your case, you can try logging in on Bungie.net with your Steam account and then authenticating Xbox to see if that helps. Otherwise, you can try clearing your browser cache, using an incognito window, using a different browser, using a different device entirely, or using some combination of these to attempt to alleviate the situation. If you're seeing any specific errors during the process, please let us know.
