At the moment it's not possible to prefill a Passphrase page with a name and a description. Example:

https://we.phorge.it/passphrase/edit/?type=password&username=foo&name=bar&description=hello

At the moment, only the username is prefilled.

To be honest it would be nice to also prefill the visibility policy and the edit policy, but this is too complicated for me, and not a good first Task.
