The automated removal of One-Time Passwords (OTPs) after a 24-hour period represents a security and efficiency measure applied to temporary authentication codes. These codes, often delivered via SMS or email, are designed for single-use verification, such as during login or transaction authorization. An example includes a six-digit code sent to a user’s phone to confirm their identity when accessing a website.
This practice enhances security by limiting the window of opportunity for unauthorized access using compromised OTPs. Once the validity period expires, the code becomes useless, mitigating potential risks associated with delayed or intercepted OTPs. Historically, OTPs remained valid indefinitely, posing a security vulnerability if they were exposed but not immediately used. Automatically deleting them addresses this vulnerability and reduces database clutter.
