Your vault holds more than passwords. Saving a bank account works the same way as a login: bank name, account number, sort code or IBAN, and any login details.
A password manager that only holds passwords leaves the rest of your life on paper. Card numbers, account details and recovery codes are the things people end up photographing and emailing to themselves.
The entry appears in your vault immediately and syncs to your other devices. Search finds it by name, and the filter chips narrow the list by type.
