We have resolved the issue preventing oauth applications from authenticating to Onshape, and all customers should now be clear to use all applications.
We apologize for the productivity that was lost during the time that applications were unavailable and we will be making changes to the product to make sure it does not happen again.

We are currently investigating an issue where oauth apps cannot properly authenticate to Onshape. We know that many of our customers use applications to get their work done and we are doing everything we can to identify and fix the issue.
