This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

-webkit-text-security is a non-standard CSS property that obfuscates characters in a <form> field (such as <input> or <textarea>) by replacing them with a shape. It only affects fields that are not of type=password.


-webkit-text-security: circle;
-webkit-text-security: disc;
-webkit-text-security: square;
-webkit-text-security: none;
