If you're using Firefox there is a tweak you can make to not give sites access to your password.[1]

Aside from that, try to avoid using auto fill, just copy the username/email and password from your manager directly.

Hi HN,

I am not a security expert and was wondering how I can secure my (Ubuntu) Linux based system from such an attack?

Background: I am using the pass password manager to copy & paste passwords all the time.

Now, I am afraid that websites like LinkedIn may have stored my clear-text password.

I researched this but only find clipboard managers. No security tools for that.

Thanks for any help.

You could run your browser in a vm , and disallow copy / pasting for that in the vm settings.
