SciTokens (https://scitokens.org/) is an NSF-funded project to implement capabilities-based authorization for distributed scientific computing. SciTokens software is Open Source, follows OAuth and JSON Web Token (JWT) standards, and conforms to WLCG Common JWT Profiles (https://doi.org/10.5281/zenodo.3460258).
Adding SciTokens support to SSH with OAuth (XCI-496) enables login using standard JWTs as an alternative to Globus Auth tokens. An initial implementation is complete (see: https://github.com/XSEDE/oauth-ssh/pull/69).
Comments
There are comments for XCI-694 that can be viewed with XSEDE authentication.
