Time-based authentication leverages a mechanism where passwords are only valid for a very limited time, such as in one-time passwords (OTPs) used in 2FA systems. After the time lapses (typically 30 seconds to a few minutes), the password cannot be used again, enhancing security by minimizing the risk window for password theft or reuse. This method contrasts from passwords or PINs that do not expire by time but perhaps after several uses.
