Hi,
As previously mentioned, You don’t currently have a support plan that includes Email support. You can find our community support forum here: https://community.n8n.io/ to create a new post you will need to register an account and click on the “New Topic” button once in there it provides a template to be completed.
You can also find how to reset your password if you have not configured the email server in our documentation here: CLI commands | n8n Docs
I use this command n8n user-management:reset.
