Categories are great for organising types of passwords/secure/secure information. Additional categories provides greater flexibility to the user.
Additional Category - Device
Used for physical devices such as laptops, phones, memory sticks, printers and other equipment (so many devices have login passwords of some kind). Suggestion of fields to include: username, password, serial number, mac address, service code, model.
Use case: I have used server to store all these devices along with actual servers as the server category intended. The range of devices and quantity is prohibitive to sorting and accessing information. The range of devices stored here usually contains username/password along with disk encryption keys/passwords for bitlocker etc.
I believe a dedicated category for devices to differentiate from servers would be beneficial for many users.
Additional Category - Key
Used for Keys as in SSH & encryption keys. A new Key item would be pre-populated public & private key fields.
Presently Password is the go to category for such information, though in my use case, these have a name prefix to sort and identify SSH & encryption keys vs other generic passwords. I believe the separation of keys from passwords would be beneficial for many users, and particularly complementary with the other development/engineering centric categories.
