You can now update the credentials for a Custom Upstream directly from the Pantheon Dashboard — no support ticket or new upstream required. Previously, changing a private repository's access token meant either creating a new Custom Upstream and switching each site over to it, or contacting Pantheon Support.
What's new
- The upstream Settings page now has a Repository credentials section that shows whether credentials are set and lets you update them — a GitHub personal access token or a Bitbucket repository access token.
- The stored credential is masked and never displayed back in the Dashboard.
Changing the repository URL still requires creating a new Custom Upstream.
For steps, see Edit an Existing Custom Upstream.
