Sign in to Azure Service Bus with Entra ID in Service Bus Explorer 6.3.1

Service Bus Explorer 6.3.1 lets you sign in to Azure Service Bus with your Microsoft Entra ID account. The sign-in happens in your browser, and no shared access key is stored on your machine. Entra now sits in the connect dialog's Authentication list, next to shared access signature.

Open File, then Connect, which now also answers to Control N. Set Authentication to Entra and type the namespace endpoint, with or without the sb:// prefix. The tenant ID and the entity path are optional. Click OK and finish signing in in your browser.

Leave the tenant ID blank and the app uses the organizations endpoint, which accepts work or school accounts only. A personal Microsoft account needs the tenant ID, and it must already be a guest in that tenant with a Service Bus data role. Tenants you use often can be listed under Options, Authentication, and the connect dialog offers them.

A saved Entra connection holds metadata only: the endpoint, Auth Mode equals AAD, and optionally the tenant, the transport type and the entity path. To switch users, choose File, Log out from Entra. It clears the app's cached sign-in, though your browser may still pick the same account.

Event Hubs namespaces work too. The app asks for a Service Bus token first. If the namespace rejects it, the app retries with the Event Hubs scope and loads the event hubs, for the sender test and the partition listener as well. A hub name in Entity Path narrows the tree to that one hub.

Entra mode runs on the public Azure cloud only, so Azure Government and Azure China are not supported. Sign-in is interactive, and managed identity, Azure CLI and service principals are not included. Notification Hubs and Relays don't load in Entra mode. A shared access signature connection still covers them.

Subscriptions catch up with queues. Right-click a message in a subscription's Messages or Dead Letter grid, and you get Select All Messages, on Control A, and Save Selected Message Text as File, which writes only the body. Several selected messages each get their own numbered file.

A fix: Control F inside a message text box used to jump to the tree filter. Now the text box keeps it. The File menu is renamed too. Connect using SAS is now Connect, the Event Grid item is now Connect to Event Grid, and Log out from Entra is new.

Upgrade with Chocolatey, WinGet, or the download on the GitHub release. The release notes list no breaking changes. The config file in the app folder is overwritten on upgrade, so keep your settings in the User Configuration File. If you need managed identity or a sovereign cloud, keep your current connections. On public Azure, 6.3.1 lets you sign in to Service Bus with Entra ID.
