'How to change the default 30s for the google authenticator
Google Authenticator defaults to refresh the verification code every 30s. I want to change it to refresh the verification code every 24 hours. How can I achieve this? In addition, I read the source code and found a value. After modifying it to 86400 (24h), the installation does not take effect after the compilation is completed. In source code; \src\google-authenticator.c 793lines. source code

RFC 6238 states that:
We RECOMMEND a default time-step size of 30 seconds. This default value of 30 seconds is selected as a balance between security and usability.
I'm not aware of any way to change this value for Google Authenticator, and 24h seems very long.
