Signups when UVPA doesn't exist

If device doesn't support passkeys i want to sign user up and sent him account confirmation email and then do the same every time he signs in, how should i approach doing this?

The SupportComponent will send a {:passkeys_supported, false} message to the parent LiveView in that case. With this message, you might set a @passkeys_supported? assign, which would be used to remove the webauthn components in the template. Email magic links seem like a sensible fallback, and there are several articles online for implementing magic link authentication in Phoenix.

If you have used the mix wac.install task or have a functioning LiveView for registration and authentication, it may be relatively straightforward to implement magic links as a fallback. This is a feature that would be nice to include in the code generated by wac.install, though I have some hesitation that it will lead to requests for other fallbacks and configurability that may be hard to support. The results for passwordless on hex.pm don't give me much confidence about including them in this package.

At a glance, ueberauth_passwordless seems like a decent starting point. I've had good success with ueberauth_google on a project recently.

Thanks, i will soon provide feedback on how the implementation went once i solve my previous issue.

And regarding builtin "magic links as a fallback" feature, while ease of implementation of that feature is a valid reason not to make it builtin, i don't think people requesting more features is. You can just close the PRs/issues as it is your project and you are entitled to doing anything you want to do with it.

And if someone really wants some feature that badly, there's always a "fork" button.
