The YubiKey goes into your PC or Mac’s USB port and requires no software to be installed. When it’s time to generate a one-time password, simply press the key’s button and the password is automatically typed on the screen.
Your OneLogin account can be configured to require two-factor authentication for everyone or just select users. And users can register their own credentials during the login process, which makes large scale deployments a breeze. When a user has successfully been authenticated with a username and password, a one-time password is generated by a light press of the button on the YubiKey – the one-time password is automatically entered and the user logged-in.
The main advantage of the YubiKey as a second authentication method is its ease-of-use. You don’t have to start an application and manually type in a one-time password. Just press the YubiKey and it happens automatically. The YubiKey can be carried on your key ring, is very sturdy and even goes in the washer. Read more about Yubico here.
