The concept refers to the automatic removal of One-Time Passwords (OTPs) from a system after a period of 24 hours. This feature ensures that these sensitive codes, used for authentication, are not stored indefinitely, thereby reducing the risk of unauthorized access if the storage medium is compromised. For example, a banking application might automatically purge OTPs sent to users after 24 hours, rendering them invalid even if intercepted after that timeframe.
Implementing such a system offers multiple advantages. Firstly, it significantly bolsters security by minimizing the window of opportunity for malicious actors to exploit old OTPs. Secondly, it aids in compliance with data retention policies and privacy regulations, as it limits the storage of potentially sensitive user data. Historically, the concern surrounding the longevity of stored OTPs has increased with the rising prevalence of data breaches, leading to the adoption of automated deletion mechanisms as a crucial security measure.
