How does family access Vault

Hi there,

From the website I've created a vault for a family member. I've shared the vault by adding their name/email. Now how do they actually access it? There are no other options to click on. Shouldn't they get their own login credentials? They have not received an email from 1password on what to do next. Every "Help" article I click takes me to the same page on how to create and share a vault, and I follow those steps, but nothing actually tells me how they are supposed to access it.

Thanks in advance
