'Edit Data Source' Unavailable for Google BigQuery Data Sources

The 'Edit Data Source' option may be grayed out for some published data sources. Additionally the information displayed says "Connection not supported by web authoring. Use Tableau Desktop to edit data source."

Cause

Editing data sources on the web does not support OAuth data sources that use 'managed keychains' for authentication. The "embedded password" option in the publishing dialog in Tableau Desktop corresponds to 'managed keychain', while the 'Embed <Google BigQuery email>' option corresponds to 'saved credentials'.

For more information, see:

• Understand supported connections 
• Scenario limitations with managed keychain

Note: Another possible reason for the 'Edit Data Source' option being unavailable for a data source is that the data source uses a connection facilitated by Tableau Bridge.
