The site is http://nab.com.au/
then click on Login opens a new fullscreen window, this is where the issue occurs. I am aware this is 99% a issue with the coding of the banking website, but I thought someone might be able to help even thought it is difficult to test a fix without being a NAB customer.
I had an issue using Chrome to login with Internet banking for quite a while. It would not autofill correctly. It worked in Firefox and IE.
I deleted the entry from my saved sites and manually entered the site and saved it again. Now I get the error below when using Lastpass, in Chrome 7, Firefox 4.0b6 and IE9 beta as well:201001: You have entered your NAB ID or password incorrectly or are not currently registered for Internet Banking. Please select OK to re-enter or Cancel to return to the Internet Banking Home Page.
Note: Having CAPS LOCK on may cause you to enter the wrong password
I actually triggered some sort of event while testing this across all my browsers, and I got blocked out of my account and had to reset my password
I can only enter the site if I manually enter my password so I think it has something to do with not liking autofill instead of physical entry. I have deleted the password from lastpass and now have to enter it manually, but this defeats the purpose of using Lastpass (which I love) as the NAB is one of four sites where it is critical I have security, the other 100 sites in Lastpass are just for ease of use.
