The best thing about HTML5 attributes is that they have no effect whatsoever on unsupported browsers, so older versions of Internet Explorer will act as if they are not present and just run the Java Script validation as before.
Of course that only works if your login system reports failed login attempts to a system log file.
Another method is to display what they've entered as part of a 'confirmation page'.
The problem here is that you're making the password visible in the browser, browser cache, proxy, etc.
In most browsers - those that support Java Script 1.5 (Firefox, Chrome, Safari, Opera 7 and Internet Explorer 8 and higher) - you can use more powerful regular expressions. The code presented above is fine in that it checks everything that we wanted to check, but uses a lot of code to test each requirement individually and present different error messages.
We're going to show you now how to apply the password tests using a single regular expression.
If the purpose of registration is to confirm that the person exists, and that they have supplied a valid email address, then as part of the registration processe you a should either email them a random password or a confirmation token rather than letting them choose their own password and use it immediately.
