good to know
Before you connect
Azure Blob Storage does not expose a native S3 API — the app’s Azure preset targets your storage account’s Blob endpoint, and S3-style compatibility is more limited than on true S3 providers. Treat it as best-effort and verify your workflow.

faq
Azure Blob Storage — frequently asked
+ Is Azure Blob Storage S3-compatible?
Not natively — Azure has its own Blob API. Universal S3 Client ships an Azure preset that connects with your storage account name and access key, but compatibility is more limited than with true S3 providers like AWS or R2.
+ What credentials does the Azure preset use?
Your storage account name and one of its access keys, both found under Access keys in the Azure Portal. The endpoint becomes https://{account}.blob.core.windows.net.
+ Should I use Azure or an S3-native provider with this app?
If you’re choosing storage specifically to manage it from this app, an S3-native provider (AWS, R2, Wasabi, B2…) will give you the most complete experience. The Azure preset exists for users who already have data in Azure.
+ Are my Azure keys stored securely?
Keys are encrypted in the device Keychain and never leave your device — the app has no backend and no analytics.
