Start Using Your YubiKey

Your YubiKey needs to be registered or paired with each service or site you use it with. Many services, like Gmail, Dropbox, GitHub, Dashlane, and LastPass work with YubiKey instantly: open their respective two-factor authentication or 2-step verification settings to register your YubiKey with each service. For enterprise services, like Google for Work, Salesforce.com, Dropbox Business, Duo, Okta, and Centrify, your administrator will need to provision your YubiKey to work for you at your company.

Those with more technical expertise can configure their YubiKeys for an enormous number of uses, using our Personalization Tools, and can integrate YubiKeys with their own applications and services using free open source software from our Developer’s site.
