Quick questions

Is this cryptographically secure?

It is useful for browser-side testing and mock flows, but not a replacement for secure server-side key provisioning.

Can I add a prefix?

Yes. You can add prefixes such as mc_, sk_, or project-specific labels.

Can I generate more than one key?

Yes. Choose a count and copy the whole batch.
