@BlackDex commented on GitHub (Dec 15, 2022):

Vaultwarden doesn't support the Bitwarden Public API, so that will never work.
At this moment Vaultwarden only supports the client API, which is why your request fails.

If you really want to login this way, make sure to use the client API, which also provides a device_identifier and device_name
The device_identifier is a v4 UUID, which stays unique per device/client and keeps the same per user, even if it is the exact same device/application.
