String Obfuscator replaces characters in the middle of a string with a mask. It is useful for displaying part of a test identifier, not for securely erasing a secret from a file.
Try a disposable value
Type AB12345678 into Text. Leave Keep first and Keep last at 2, and Mask with at *. Obfuscated should read AB******78. The result updates as you type. Set Keep last to 0 and the whole part after AB becomes masked; set Mask with to # to change the visible replacement. The Copy and Download buttons use the displayed result.
Spaces and line breaks remain visible even in the masked part. If Keep first plus Keep last covers the whole string, there is nothing left to hide. Check the result visually before sharing it. This operation does not delete the original from the source document, clipboard history, or screenshots you already took; for real credentials, rotate them if exposed.

Questions you might have
- Is this a security measure?
- No. It is a presentation aid. The original value is still wherever you copied it from, and masking is not the same thing as redaction.
