There is an advanced setting that if enabled, members can have multiple individual accounts with the same email address, but they need different passwords.

1. Go to "Settings"
2. Click on "Advanced Settings"
3. Then search for "Allow Multiple User Accounts with Same Email Addresses"
4. Turn the setting "ON"
5. Click on the "Save" button

Alternatively, the Multi-Member Manager allows you to manage multiple sub accounts from one parent accounts, also using the same email but with different passwords:
