Hi David,

Welcome to the Box Community! I'm happy to help.

It looks like your Box account with this email address was confirmed. I suggest that you sign in using your Box credentials by going to this link.

To reset the password for your Box account, follow this process: Visit https://app.box.com/reset and enter the email address associated with your Box account.

Password reset links sent via email expire 3 hours after they are sent.

Hope this helps. 

Best,
