Otherwise, someone could use passwordauth to register as a username that
looks like an email address, which would be confusing to possibly a
security hole. Probably best to keep passwordauth and emailauth accounts

+ entirely distinct. Update: passwordauth never allowed `@` in usernames.
* Currently, subscription to comments w/o registering is handled by
passwordauth, by creating a passwordless account (making up a username,
not using the email address as the username thankfully). That account can be

> But it seems to me that your proposal is basic "email opt-in".. the one impact this has on (drupal) sites i know is that spammers use even those forms to send random emails to users. it's weird, but it seems that some bots simply try to shove victim's emails into forms with the spam data as they can and hope for the best... it seems this could be vulnerable as well... - [[anarcat]]

+Also, I have found a similar system called [Portier](https://portier.github.io) that enables email-based auth but enhances it with [[plugins/openid]] connect... Maybe ikiwiki's authentication system could follow the standards set by Portier? OpenID connect discovery is particularly interesting, as it could mean that using your GMail address to login to ikiwiki would mean that you go straight to the more secure OpenID / Oauth authentication instead of relying on the slow "send email and click link" system... --[[anarcat]]
