#  * Set up a vaultwarden server
#  * Have Firefox use the web vault to create an account, log in, and save a password to the valut
#  * Have the bw cli log in and read that password from the vault
#
# Note that Firefox must be on the same machine as the server for WebCrypto APIs to be available (or HTTPS must be configured)
#
# The same tests should work without modification on the official bitwarden server, if we ever package that.
