If an email address is associated with your account a password reset link will be emailed to you which will be valid for 1 hour from the time of the request.
If no email address is associated with your account and you have security questions configured you will be presented with a series of prompts to recover your password.
If no email address or security questions are associated with your account you will be asked for an email address to associate with the account and if provided the account will be flagged for moderator review. Account recovery reviews will be evaluated based on current activity logs and past activity associated with the account at the discretion of the moderator reviewing the account recovery request and will take an indeterminate amount of time. While awaiting an account recovery request without sufficient identifying information associated with the account you may create a new account and merge the two accounts if approved.
