The Fediverse is a collection of social networking services that can communicate with each other using a common protocol. Users of different websites can send and receive status updates, multimedia files and other data across the network. The term Fediverse is a portmanteau of federation and universe.

ActivityPub

ActivityPub is a protocol and open standard for decentralized social networking. It provides a client-to-server (C2S) API for creating and modifying content, as well as a federated server-to-server (S2S) protocol for delivering notifications and content to other servers. ActivityPub is the defining standard of the Fediverse, a decentralised social network of various social interaction models, and content types, which consists of independently managed instances of software such as Mastodon, Pixelfed and PeerTube, among others.

Federated Credential Management (FedCM) API - Web APIs | MDN

The Federated Credential Management API (or FedCM API) provides a standard mechanism for identity providers (IdPs) to make identity federation services available on the web in a privacy-preserving way, without the need for third-party cookies and redirects. This includes a JavaScript API that enables the use of federated authentication for activities such as signing in or signing up on a website.
