Take note of what o_e_l_e_o said above and take note about the email because they need two emails.

Users can also choose to split ownership between multiple users and email accounts, requiring these users to approve of a transaction before it can be completed.
Most of the complaints here on the forum they forgot the 2nd email and can't able to withdraw their funds from Vault without the confirmation from 2nd email. So make sure that you have access to both two emails for future withdrawal. If you don't have a 2nd email there is no way to recover them based on what Coinbase support said.
