What can be a consequence of frequently used one-time passwords?

The consequence of frequently used one-time passwords is that they can lead to indefinite changes due to resets. One-time passwords (OTPs) are designed to enhance security by being valid for only a single login session or transaction. However, if a system allows too many resets or frequent usage of OTPs, it may inadvertently open up avenues for repeated authentication requests, consuming administrative resources and potentially leading to weak security practices. Frequent resets can also create confusion and increase the chances of errors during the login process, as users may be unsure which password is currently valid.

This situation highlights the importance of balancing security measures in authentication processes. While OTPs are a robust method for securing access, their handling needs to be carefully managed to avoid these pitfalls, thereby reinforcing the need for well-defined policies around their use.
