A screenshot caption or image filename can expose the same account details as the image itself. Playlist links, activation keys and device identifiers sometimes get copied into captions while someone documents a setup. Use descriptive nonsecret labels and inspect both the visual content and surrounding text before publishing.
Review more than the pixels
A cropped image can be clean while its filename still includes a username or its caption contains a complete service link. Public content systems can index those text fields. Redaction should cover the whole published asset.
Use neutral descriptive language
A caption such as “Player account setup screen” explains the image without exposing a key. Avoid placing actual credentials in alt text, titles, download names or structured metadata. Accessibility text should describe the useful visible context, not hidden private values.
Replace exposed assets properly
If a sensitive screenshot was published, remove or replace the original public file rather than merely drawing an overlay in the page. Consider whether the exposed credential needs rotation through verified support. Search caches may take time to update.

An example to work through
A screenshot named account-demo-password123.png still discloses sensitive text even if the visible password box is blurred. Use a neutral filename as well as a redacted image.
