Common questions
Does this use the Nano ID library?

It implements the same compact ID concept directly with Web Crypto and unbiased index sampling; no remote service is involved.

Are numeric IDs suitable for security tokens?

Usually not. Numeric alphabets provide much less entropy per character, so use a longer URL-safe ID and a server-side security design for tokens.
