Also, from the Kagi privacy pass FAQ at https://blog.kagi.com/kagi-privacy-pass#faq:
*Do you plan to allow purchasing privacy pass tokens without having an account?*
Yes, this makes sense. This is possible because technically the extension does not care if you have an account or not. It just needs to be 'loaded' with valid tokens. And you can imagine a mechanism where you could also anonymously purchase them, eg. with monero, without ever creating an account at Kagi. Let us know *here* ( https://kagifeedback.org/d/6163-kagi-privacy-pass ) if you are excited about this, as it will help prioritize it.
