The persistence feature is enabled by default. Setting the value of the `autocomplete` attribute to `off` disables this feature. This works even when the `autocomplete` attribute would normally not apply by virtue of its `type`. See [Firefox bug 654072](https://bugzil.la/654072).
 
+## Accessibility Concerns
+
+If a form does not have `autocomplete="off"`, the browser will still attempt to autocomplete the form fields, which can make it difficult for screen readers and other assistive technologies to navigate the form, potentially causing these users to be unable to complete the form. the lack of autocomplete or autocomplete=off and so on is something that automated accessibility tests would reliably catch and flag. This affects the usability of a form specifically but also the accessibility compliance of the website as a whole.

+## Example

+### HTML
+
+```html
+<form>
+  <label for="username">Username:</label>
+  <input
+    type="text"
+    id="username"
+    name="username"
+    autocomplete="on"
+    aria-required="true"
+    aria-label="Enter your username" />
+  <label for="password">Password:</label>
+  <input
+    type="password"
+    id="password"
+    name="password"
+    autocomplete="on"
+    aria-required="true"
+    aria-label="Enter your password" />
+  <input type="submit" value="Submit" />
