Change Password display in plain text?

Sorry if this has already been answered, but I couldn't find it on the forums or a search engine.

 

When using saved log-ins in the Norton Identity Safe, is there any way to prevent  the passwords from being shown in plain text on a web site's login form?

 

I'd like to prevent other people from seeing my passwords if I'm showing them something on my PC.

 

Thanks,

R
