Is login assistant secure?

I use cnss 20 (newest one just dwnld)  Two major questions:

I run win7 ie9 all up to date and have norton set for admin settings only.

 

1. Is nortons login assist secure since the login appears in full alphebetic form on screen when you use it, right in tool bar? (feels like it should be in console on your pc not in tool bar)

 

2. Why is only appearing on one limited user account and not the other? ( both limited users)

 

 

 

Thank you! :)
