Read full descriptionHide full description
TOPT Calc calculates a TOTP (Time-based One-Time Password) code based on a known secret key. The application is more secure than standard ones because: - it does not know anything about the user's account - it does not store anything internally - the secret key can be stored separately (e.g. on paper)
