The HTML <keygen> disabled attribute is a boolean attribute that indicates whether the <keygen> element is disabled or not. It is used to keep a user from using an input field until some conditions would be applied to it.
Note: We can use JavaScript to change the value of the disabled <keygen> element.
Syntax:
<keygen disabled>
