EinmalpasswortGeneratoren
EinmalpasswortGeneratoren, often abbreviated as OTP generators, are software or hardware devices that produce a one-time password or token. These codes are used for authentication purposes and are valid for a single login session or transaction. The primary goal of using an OTP generator is to enhance security by mitigating the risk of password reuse and interception. Traditional passwords, if compromised, can be used repeatedly by attackers. One-time passwords, however, expire after a short period or a single use, significantly reducing the window of opportunity for unauthorized access.
OTP generators typically operate based on one of two main principles: time-based one-time password (TOTP) or
These generators can be implemented as standalone hardware tokens, such as key fobs, or as software applications
