YubiKey Set-Up And Use:                                                    Two Factor Authentication Using Hardware (YubiKey)   Secure Google, Bitwarden, LastPass

Your YubiKey is the size of a thumb (flash) drive and plugs into the same place (USB port) on your laptop.

Pressing or tapping button is done with a light touch especially when plugged into a port.

The YubiKey is a device that makes two-factor authentication as simple as possible. Instead of a code being texted to you, or generated by an app on your phone, you press a button on your YubiKey. That's it. Each device has a unique code built on to it, which is used to generate codes that help confirm your identity. Press (tap) the button softly and you can log in.
