WebFinger allows you to be discovered on the web using an identifier like [email protected] — similar to how email works, but for your online identity.
Why is this useful?
How it works:
When someone searches for @[email protected] on Mastodon or another federated service, their server asks your WordPress site: “Who is this person?” WebFinger answers that question by providing information about you and links to your profiles.
Technical details:
WebFinger is an open standard (RFC 7033) that enables discovery of information about people and resources on the internet. It works by responding to requests at /.well-known/webfinger on your domain.
