Anonymous-style ShareX uploads

Upload screenshots with ShareX without storing them to your account.

Use Biohost temporary mode for ShareX uploads when you want quick screenshot links that behave like anonymous temporary uploads while still using secure API key access.

What anonymous-style ShareX upload means

With Biohost, ShareX temporary mode is designed for users who want the convenience of anonymous-style temporary links without opening the browser for every upload. You still sign in once to generate the API key, but the uploaded files can follow the temporary upload workflow instead of being saved to your account history.

This gives you a practical middle ground: the upload endpoint is protected by a key, while the files themselves can be treated as disposable links for short-term sharing.

When to avoid account storage

Not every screenshot belongs in a permanent dashboard. Error messages, quick UI notes, single-use images, and temporary Discord references are often better as expiring links.

If you later decide that your ShareX uploads should be retained, generate a new Biohost ShareX config in account mode and import it into ShareX.

Privacy notes for ShareX links

Temporary and anonymous-style uploads are not the same as encrypted private storage. A Biohost link is still a link, and anyone who receives it may be able to open the file unless the file is protected.

Avoid uploading secrets, private documents, account tokens, or customer data through a quick screenshot workflow. For sensitive files, use controlled access and keep the generated ShareX API key private.

  • Do not share your .sxcu config publicly.
  • Revoke exposed API keys immediately.
  • Use account mode when you need review and deletion controls.
  • Keep sensitive screenshots out of public channels.
