Frequently asked questions
- Why does clipboard read ask for permission?
- The Clipboard API requires explicit user permission for reading to prevent silent data theft. Writing usually does not require a prompt.
- Why is the Clipboard API not available?
- The Clipboard API requires HTTPS (secure context) and a modern browser. Older browsers fall back to document.execCommand which is deprecated.
