How to protect myself from keyloggers and screen capture programs?

[darkmatter2020]

I have a Ubuntu home PC. I often use this system to enter passwords to various websites. Some sites also offer a graphical on screen keyboard to protect from keyloggers. However, I suspect that even the on screen keyboard is not safe from malicious software which records the computer screen. I want my passwords to be safe from such programs. Of course, I do ensure that I don't install insecure programs but I would like to have an additional layer of security.

Use 2FA. Nothing else is sufficient for the paranoid. Look for a u2f compatible device for most websites. Unfortunately, most finacial websites don't support u2f, preferring to use older tech like TOTP. Yuck.

For MFA, Google provides an easy setup for desktop.
