You can access the real-time counter with Zephyr kernel API, such as k_uptime_get() or k_uptime_get_32().

Hope this post can help. If not, Please create a new support case for the RTC setting which is away from the original scope, and I will be out of the office next week.

Hi,

We do not have any TOTP samples. However, we have a set of crypto samples. You can then use our cryptography functionality to implement TOTP, for example using the code you link to.
