For most web pages that have a username and password dialog, browsers will prompt the user if they want to save the credentials for that form:
When IE is configured to ask you the question, then it will ask or not depending on the way you submit the form.
When submiting using an input type="submit"
(i.e. a submit button), then IE will ask you if you want to save the password.
If you use javascript to submit the form, like this document.getElementById('Form1').submit()
, it will not ask you to save the password.
Try this HTML, in IE (I didn't test other browser yet):
Html code:
Home Page
If you check the box to never ask again, then you can configure that in IE options:
Tools > Internet Options > Content > AutoComplete
