Questions about the logon shell cannot successfully enter the user name password

Recently found in the group feedback, login layer can not successfully enter the user name password situation, roughly looked at, a little summary:

I encountered the login can not successfully enter the user name password situation there are two, one is the positioning error, one is not the focus element, the two look similar, but the actual somewhat different, the following will be described in detail below:
