One account for the grown-up. Each child is a profile inside it — never a user, never an email address of their own.

At least 8 characters. No uppercase-and-a-number rules: length is what matters, and those rules just produce passwords people write down.

Two fields. That is the whole form.

Everything else is asked later, in the moment it is needed, where we can explain why. Going from four fields to three raised completions by about half in 40,000 forms.

We never ask for a child's name, email, photo or date of birth.
