About
Onion sites are websites on the dark web that use the .onion top-level domain and are only accessible through online routing through Tor.
OpenID is a decentralized authentication protocol based on OAuth 2.0 that enables applications to verify a user's identity through an external identity provider instead of managing credentials directly.
It adds an identity layer on top of OAuth by issuing ID tokens that confirm who the user is, supports single sign-on across multiple services, and allows retrieval of basic profile information.
