CENTRALIZATION OF AUTHENTICATION SERVERS FOR DIFFERENT RESOURCE SERVERS

Methods and systems for centralizing disparate authentication servers using scopes are described herein. A computing device may receive, from a client device, a first access request comprising authentication credentials and first scope data. The computing device may then send, to at least one first authentication server associated with the at least one first resource server, a first token request. The computing device may then receive a first token and provide that token to the client device. The computing device may then receive, from the client device, a second access request comprising second scope data. The computing device may send, to at least one second authentication server associated with the at least one second resource server, a second token request. The computing device may then receive a second token and provide that token to the client device.
