Hi Luciano,
but I wonder if someone know why it doesn´t work
According to the Microsoft's MSDN, IE on PocketPC is based on IE 4.0. It does not support DHTML. This means in order for the page to work on that browser, you'd have to press a "submit" button, have the web server generate the password, then return it to your browser. Needless to say, this means you'd have to place enormous trust with passwordmaker.org.
Someone else brought this issue up recently. Does your PocketPC support Java? His did, and he suggested he'd wait for the Java mobile version.
My concern with using the online version in public computers is that the generated password is visible and there may be keyloggers and such.
If this is a concern, we can add a checkbox which, when checked, turns the password to ******. When unchecked, it shows the password in clear text. The checkbox setting would be stored in a cookie like the rest of the settings, so next time you visit the page it has the same value as before.
By the way, if you always use copy/paste of the generated password, you'll defeat any keylogger -- regardless of whether or not the password is hidden with ***** or not.
Regards,
Eric
