The previous account cannot log in

Respected forum administrator, the previous account was registered using duckduck, with a random email. Now I only have the initial account, initial email, and initial password. However, emails cannot be automatically sent to the original email address anymore. What should I do in this case? I still have the activation email from the past. The current issue is that the password login prompts an incorrect password.
