I like it, should save time from having to build and host a custom password-less auth and so far everything (ui, demo) looks pretty good for a new product (some minor issues like the the custom ui editor is a little janky when uploading a logo, etc). I think with time this will prove to be great.

All my feedback/requests is related to building trust since this is an auth service. I'm sure they are working on many of the following, but want to put this down:

1) Ability to send custom emails and copy from own domain email to have trust with visitors

2) Custom css/html, custom text - really it needs as much custom as possible for everything because it's important visitors don't think it's some phishing popup - even how the service / privacy policy links goes to onzauth and not the website's own policies is odd for a visitor. I also think since it's so different from the password world that people are used to that letting us experiment with how to present is important - I don't think the current onz-auth flow as clear as it could be and don't want to be dependent on that ux.

3) Feeling secure in the company behind this service to have more confidence this service won't die since auth is so important - more info on the company, fixing the zailky link in the footer, details on gdrp or any other policies, fixing the slack invite link in the footer (off topic but i would prefer discord tbh since I'm on the free plan and already subscribed to a few slacks I can't join without paying) ,

4) Some kind of documentation and flow on how to prepare for the slim chance onzauth suddenly disappears - maybe a way to backup or sync the data.
