Is there a way to connect to Databricks with server hostname and http path, instead of personal access token?
Hi there! Thanks for asking this. Unfortunately, personal access token is the only authentication method available for Databricks in the catalog explorer.
I opened up an issue in the Positron repository to flag this request! Feel free to give it a

Hello there, @wzhou35! 
I wanted to update you that connecting with server hostname and HTTP path is now possible.
Since this thread was started, we introduced Data Connections, a new way to connect to databases and data warehouses in Positron. It supersedes the Catalog Explorer extension, which is no longer included.
For Databricks, every connection is defined by the workspace's server hostname and the SQL warehouse or cluster's HTTP path, and you can authenticate with:
- A personal access token
- OAuth user-to-machine (U2M), which opens your browser to sign in
- OAuth machine-to-machine (M2M), using a service principal's client ID and secret
- On Posit Workbench, the session's managed credentials
Once connected, you can browse Unity Catalog catalogs, schemas, tables, views, and volumes, and preview tables in the Data Explorer. See the Data Connections documentation for details.
