There are many options for account configuration at Casa, including having multiple Casa accounts if this suits your needs. Having multiple accounts is permissible within our terms of service.
- Casa Standard membership includes a Casa Pay wallet, as well as a 3-key vault (with the option to have a subaccount).
- Casa Premium and Private Client memberships include Pay, a 3-key vault (with the option to have a subaccount), as well as a 5-key vault (with the ability to add up to four subaccounts).
If you want funds to be protected by different sign-in credentials or different keys (or even if you just want them completely separate for easier record-keeping or to meet self-directed IRA requirements), you might want to create multiple completely separate Casa accounts. Creating multiple Casa accounts is encouraged if it meets your needs, and permissible within our terms of service.
If you want to set up multiple accounts, you'll need a few things:
1. Unique email addresses:
Since you sign into the Casa app using your email address, you will need a unique email address for each account you want to open. You cannot create multiple accounts using the same email address.
Some email providers, such as Gmail and Proton, have a feature called "aliases" which enables you to have a different email alias within the same email account by adding a "+" sign before the "@" sign in your email address.
For example, if your email address were "example@gmail.com," you could create a Casa account with that email address, but also "example+casa2@gmail.com" and the emails for both Casa accounts would go to the same "example@gmail.com" email inbox.
You may also set up your accounts with completely different email addresses, which can increase your privacy.
2. The Casa app:
No matter how many memberships you have, you will always manage all of your accounts through the Casa app. You can sign in or out of as many Casa accounts as you'd like on the same mobile device.
The mobile key, which is stored on your phone and backed up encrypted to your phone's integrated cloud account, will not be affected by managing multiple Casa accounts on the same phone and cloud account. A distinct key will be generated for each account.
To switch accounts, go the "Account" tab in the Casa app and scroll down to "Sign Out." Then sign back in to your other account using your other email address and password. You may want to force-quit the app and relaunch if you run into any issues when changing accounts.
For redundant backup of the mobile key and bitcoin Pay key, consider printing out the encrypted QR backup(s) for each unique Casa account you have.
3. Hardware device(s):
For any paid membership with Casa, you will need to set up the hardware key(s) for your 3-key or 5-key vault separately for each account. Just like with the Casa app, you can use the same hardware devices for as many Casa accounts as you'd like. For best security practice, we recommend using unique hardware devices for each Casa account (though if you do choose to reuse the same devices, the Casa app will work perfectly fine with the same hardware devices on multiple accounts).
Whatever your reason, the Casa app is prepared to support as many accounts for you as you would like to use.
