Short answer: a lot 😉 its an authentication protocol to have a single identity provider take care of all your users passwords, access rights etc., like those “login with Facebook” buttons.

It’s a bit of advanced topic, but a solid way to minimise authentic based alley on username and password.

Just tried it, and liked it. Too bad there isn’t support for OICD right now.

I’m really curious about Papra, but don’t see the benefits it provides over paperless. Besides, I won’t migrate unless there is a tool to brings over the tags, metadata etc…
