Google Token (HOTP)

HMAC-Based One-Time Password - HOTP - token is a way to verify a user's identity using a code generated, similar as a virtual HOTP tokens, in the physical device. If the user has enrolled this token, when asked to enter the one-time-password (OTP) when logging into the application, the user reads OTP from the device and insert into the system. If the OTP is entered correctly, the user's identity is verified and the login occurs.

The difference between HOTP and TOTP types of tokens is that HOTP generates OTP based on some instruction - most often a button in application. TOTP, on the other hand, generates a new OTP every 30 seconds.
