Can you add a password to the about:logins tab?

[LuisVaYo]

I just have to know that in the about:logins tab, are all my username and passwords, really really exposed, so, if you can add a "non-salvable" password to this tab to increase the protection of that sensitive data, that would be great.
Sorry for my bad english, it's not my natural languaje.

Thanks in advance.
