About Yubico Authenticator 2.1.0
Yubico Authenticator allows you to use a YubiKey to store OATH credentials (TOTP and HOTP supported, as used by Google, Microsoft, Dropbox, Amazon and many more) used for 2-factor authentication.
Storing the credentials on an OATH enabled YubiKey ensures that your credentials are safe, even if your phone is compromised.
It also makes it easy to move between multiple Android devices.
