The FIDO U2F standard allows for two-factor authentication with web services. It protects your account by using a hardware Security Key in addition to your username and password. It has been deployed successfully by large services, including Google, Facebook, Dropbox and Salesforce.
Our SDK provides a FIDO client for Android that works with Security Keys (FIDO authenticators), such as YubiKeys, over NFC and USB.
Supports a wide range of Security Keys, such as the YubiKeys 4 and 5 series as well as Nitrokeys. Security Keys can be directly connected over USB-C and NFC. USB-A keys require an additional USB OTG cable.
