oauth

"OAuth (short for open authorization) is an open standard for access delegation, commonly used as a way for internet users to grant websites or applications access to their information on other websites but without giving them the passwords." - https://en.wikipedia.org/wiki/OAuth

oauth 1 is incompatible with oauth 2, and in 2025 oauth 1 is considered legacy and should not be used.
