Restrict account registration to email-verified users

You can require all new accounts to be verified by email. This prevents malicious admins from registering accounts without email verification.

Prerequisites

• SMTP must be set up and n8n must be able to send emails.

How to restrict account registration

Set the environment variable N8N_INVITE_LINKS_EMAIL_ONLY to true. This locks down your instance so that only users with verified email addresses can register.
