Arta allows you to set up multiple accounts of different types not multiple accounts of the same kind.
For example, a member can set up an individual account and a trust account but cannot set up two individual accounts for the same person.
Please note that you'll need a unique email address for each account at this time. Arta does not currently support the ability to log in to multiple accounts with a single sign-in but we're working hard on building out this functionality for a future release.
If you need help setting up or accessing an additional account, please email us at firstname.lastname@example.org. We're here to help!
