Yubico makes this amazing device that supports two-factor authentication. The YubiKey. It has two slots that can be configured for different services. I have slot one configured for OTP (One Time Password) and one slot configured for a very secure static password. To use slot one, you place your finger on the gold “y” emblem that’s lit by a green LED. To use slot two, hold your finger down for 3-4 seconds.
This works great with LastPass so that entering a password for any site takes just the touch of a button. Every site and app can have a very secure password that I never have to remember. And logging into my laptop is the same. Slip the key into the USB slot and hold the key for 3-4 seconds and I am logged in!
I love the added security and ease. When I worked for the Government I had an RSA OTP that I loved. In fact getting my user’s linux machines to work with it was one of my first tasks as an admin. OTP is my preferred method.
