Aside from TOTP, as pointed out by TOTP: - the Yubikey is a hardware authentication token (with various modes - in particular, the "type my password" mode can be plugged into nearly anything) - companies like Duo Security sell two-factor authentication - ssh-agent (part of OpenSSH) allows you to keep authenticating, with or without confirmation - you can get a lot of security from doing your web browsing and your development/system administration on different machines Of course, it's hard to recommend something without any details about your situation or what you're looking for. Also, there is no conspiracy. People just don't care that much about security.
