Touch ID for Duo
Touch ID is a fingerprint recognition feature included in recent Apple MacBook computers. Touch ID can be used as a second-factor method with Duo in some circumstances. Duo considers Touch ID to be among the more secure second-factor methods, and it may also be more convenient for some users than other methods. Currently Touch ID for Duo will only work in the Chrome web browser.
