For confluence cloud OAuth2.0 is supported , I want to know if OAuth2.0 supported by confluence on-prem i.e DC and Server.
Does confluence on-prem server and Data center versions support OAuth2.0?
As per the documentation,
Confluence Data Center and Server provides APIs to allow external services to access resources on a user’s behalf with the OAuth 2.0 protocol.
Kindly checkout Confluence OAuth 2.0 provider API for more information. Hope this helps.
