Yes, I'd like to clarify Timeflake (and many alternatives suggested) is NOT meant to be used for security.
There's an important note on the readme about this:
> Since the timestamp part is predictable, the search space within any given millisecond is 2^80 random numbers, which is meant to avoid collisions, not to secure or hide information. You should not be using timeflakes for password-reset tokens, API keys or for anything which is security sensitive. There are better libraries which are meant for this use case (for example, the standard library's secrets module).
