Prevent Chrome from prompting to save password from input box?

Instead of using input type password, use type text with style set to style="-webkit-text-security: disc;" which will replace the characters with dots.

<input type="text" id="password" style="-webkit-text-security: disc;">

There are other options to using the dot:

input { -webkit-text-security: none; }
input { -webkit-text-security: circle; }
input { -webkit-text-security: square; }
input { -webkit-text-security: disc; /* Default */ }

Answer found here: how to disable save password prompt in chrome

One solution or workaround is to add <input type="password" style="display:none"/> above the real password input box. Chrome only tries to save the first password it finds and if it's blank it won't throw up the dialog to save it.
