Feature Request: turn off authentication

[max-tet]

I am hosting a single-user instance behind a reverse proxy which handles authentication. For that reason, no additional password is needed. However, I found no way of disabling the password prompt.

Ideally, there would be an environment variable like DISABLE_AUTH or something like that.

PR welcome, probably an easy one :)

I was attempting to npm install it. But I see a bunch of errors and spotted this line: gyp verb which failed Error: not found: python2. Is there really a dependency that need Python 2?

This should probably be upgraded asap. I'd rather wait with contributing until then instead of installing the outdated Python 2 for it.
