Security Keys will remain a tool for early adopters and organizations particularly worried about security. Physical security keys are already supported by a number of companies and products such as Google, Dropbox, and Facebook, Twitter as well as browsers like Google Chrome, Firefox, and Opera. Most major password managers also now support U2F, including Dash lane, KeePass, and Last Pass. Yubico offers some of the most popular options at this time, including the YubiKey, of which options for both desktop and mobile are available. Security keys are coming in at around $20 each, but they’ve been slow to catch on with consumers. It just looks like a physical key but is still your best way of keeping yourself safe.
