Plain language
The identity of a website—its address—that browsers use to keep one site from pretending to be another.
As stated in the literature
The (scheme, host, port) tuple browsers use to scope trust and enforce the same-origin policy; cited as the precedent for scoping a tool server's identity so a stranger can't impersonate a trusted name.
Also called: web origins, origin
Why it matters: It's how browsers stop one website from impersonating another, and the same idea can keep a stranger from posing as a trusted tool server.
For example, a browser treats 'https://mybank.com' and 'https://mybank.com.evil.com' as different origins, so the fake one can't reach into the real one's data.
