Add a password manager on ghostty

[petrocino]

Hello there.
First of all, thanks for the excellent terminal. I'm trying to move from iTerm2 to ghostty on both home and work at my Macs.

I would like to request a new feature: an internal password manager.
With iterm2, I have a password manager build in, which make login on multiple ssh hosts easier.
Also, when I am connected to a server and need to perform a sudo su - on it, with just a shortcut I can add it directly to my prompt.

How can I adapt it to use with ghostty?

Tks,
Alessandro.
