XSEDE users have the ability to delegate a short-lived certificate issued by the XSEDE MyProxy service to a science gateway using the XSEDE OA4MP (OAuth for MyProxy) service.
The enhanced OA4MP service now supports both the OAuth 2.0 and OpenID Connect protocols. XSEDE encourages science gateway developers to start phasing out use of OAuth 1.0a in favor of the newer OAuth 2.0 and OpenID Connect protocols. This enhancement is most useful to software/service developers that integrate with XSEDE’s security services.
More information is available on the XSEDE OA4MP page.
