Time-based one-time password (TOTP) is a computer algorithm that generates a one-time password (OTP) uses the current time and secret key (seed). This algorithm is evolution of HMAC-based One-Time Password (HOTP) algorithm.
HOTP algorithm specifies an event-based OTP algorithm, where the moving factor is an event counter. A time-based variant of the OTP algorithm provides short-lived OTP values, which are more security and eliminates the out-of-sync problem. TOTP algorithm can be used across a wide range of network applications, from remote Virtual Private Network (VPN) access and Wi-Fi network logon to transaction-oriented Web applications.
1. Install the Protectimus TOTP Burner app on an Android smartphone that supports NFC.
2. Scan the QR code containing the secret key with the Protectimus TOTP Burner app.
3. Press the button on the token and place it near the NFC antenna and tap "Continue".
4. Generate a OTP with the token and enter it into the service where you're setting up 2FA.
