welcome to the n8n community @Zyko
Are you using n8n Cloud or a self-hosted instance?
If it’s n8n Cloud, I’d use the password reset option on the login page first. If you don’t receive anything, the next step is to contact [email protected] with your workspace details.
If it’s self-hosted, there’s no central admin , the administrator is whoever manages that server. In that case, I’d reach out to your internal team or the person who deployed n8n, since only they can reset access or update the authentication settings.
