This spring, when I got licenses for myself and punchcards for my kids (both under 15 years old, I ordered the stuff online. At that time, I had to create usernames and passwords for them and I saved the login info.

When it came time to report my and their crab (we all got 0 dungeness), I logged in using the same IDs and passwords from this spring. Worked pretty smoothly.

I used the same email address for all of us (my email address), but each person needs a different user ID.
