If you’re using Azure Storage, you probably use Shared Access Signatures (SAS tokens) to share data without handing out account keys. They’re super convenient — but they can also be a big security risk if you’re not paying attention.

A SAS token is basically a key — anyone who has it can get in. I’ve seen too many teams accidentally leave SAS tokens in logs, emails, or public repos. Once that happens, your data is wide open.

A few quick reminders to keep SAS tokens safe:
– Always set an expiration date — don’t leave them open forever.
– Give them the least permissions possible.
– Use IP restrictions when you can.
– Keep an eye on where they’re stored and who has them.
– Never hardcode them in source code.

It’s easy to forget that “temporary” shortcuts can stick around forever if we’re not careful. A little discipline goes a long way.
How do you keep your SAS tokens locked down? Let’s share some tips — drop yours below.
