In the login field you place your i-Name. Here your i-Name will be used as an OpenID identifier which is an open standard that allows you to manage the login process for many other sites.
When you see this symbol you can use your i-Name to login. This is a online single-sign-on system. Now you don't need to make a new username and password pair for sites which use openid.
