redact_pass.vim

This plugin switches off the 'viminfo', 'backup', 'writebackup',
'swapfile', and 'undofile' options globally when editing a password in
pass(1).

This is to prevent anyone being able to extract passwords from your Vim cache
files in the event of a compromise.

You should test this after installation to ensure you see this message is
printed whenever you pass edit:

Editing password file--disabled leaky options!
