If your product is already filed (its record shows OFFLINE), claiming it takes about three minutes: open the terminal, type ONLINE followed by your product's name, identify yourself with an email (magic link, no password), and prove you control the product's domain with a meta tag or DNS record.
If you received an email from The Director, the link in it already carries a signed seal that handles identity and ownership in one step.
Step-by-step: bring your record online.
