+# OAuth
+
+OAuth stands for **O**pen **Auth**orization and is an open standard for authorization. It works to authorize devices, APIs, servers and applications using access tokens rather than user credentials, known as "secure delegated access".
+
+In its most simplest form, OAuth delegates authentication to services like Facebook, Amazon, Twitter and authorizes third-party applications to access the user account **without** having to enter their login and password.
+
+It is mostly utilized for REST/APIs and only provides a limited scope of a user's data.
