Simplifying signup and login

Along with some best practices there are a few interesting ideas:

Allow Users to Type Their Pass­word Only Once

Com­bat Spam by Hid­ing a Javascript Textfield, Instead of Using CAPTCHA

A modal win­dow also keeps users on the cur­rent page, but it opens up at the cen­ter of the page, putting the focus entirely on the login form. This option gives you room to add sup­ple­men­tal infor­ma­tion on your login form.

Use a Ques­tion Mark Icon for the Pass­word Recov­ery Link

Users should have no trou­ble find­ing the pass­word recov­ery link on your form. Instead of using a “for­got your pass­word” link, con­sider using a sim­ple ques­tion mark but­ton that won’t take up a lot of room and get lost among other links. Because the ques­tion mark is the uni­ver­sal sym­bol for help, users won’t won­der where to go when they’re hav­ing pass­word trouble.

Make the Login But­ton as Wide as the Textfield

The login but­ton isn’t just for tak­ing action. It also lets users know what action they’re about to take. A small login but­ton has as a weak affor­dance and can make users feel uncer­tain about log­ging in.

A wide login but­ton gives users more con­fi­dence in log­ging in and is hard to miss. The button’s label also becomes more vis­i­ble so that users are clearer about the action they’re taking.
