Hey @ikabupini
Thanks for writing in.
Yes, you can definitely do so by creating a new vault and by sharing this new vault with your wife. To know more about how to share a vault, follow the steps given below and let me know if you have any concerns:
Open Enpass on your device and go to Enpass settings --> Click on 'Vaults' --> Click on + button --> Add the vault name and click on Create New --> Enter the vault password and click Continue --> Verify the vault password on next page --> Select ‘Set up Sync’ and choose a different cloud account to sync this vault.
Enter your cloud account details, follow the instructions, and wait till the sync is done.
Open Enpass on your other wife's device--> Click on ‘Settings’ --> Click on ‘Vaults’ --> Click on “+“ and create a new vault --> Select ‘Set up Sync’ and choose the same cloud account from which you had enabled sync on your device as in step 1.
Once the sync is done, the database from your device will be synced with your wife's device.
