About this tool
This scanner matches the text you paste against high-signal credential patterns and reports each hit with its line/column position and a masked preview. It is heuristic: it can miss some keys or flag harmless strings, so it complements rather than replaces secret managers and version-control scanning. All processing happens in your browser.
