@hongminhee洪 民憙 (Hong Minhee) What can be done with email, can also be done with ActivityPub. For example, I'd love to be able to register on websites with WebFinger address instead of email address. Some sites already support registration with Matrix or XMPP addresses, but I haven't yet seen WebFinger being offered
@silverpill I have that in my brutalinks link aggregator, however it doesn't work transparently for the whole fediverse because there isn't yet a dynamic way of registering an OAuth2 client[1] that would work with all web-finger capable services.
[1] there actually are at least two: RFC7591, and also IndieAuth
If you have a fediverse account, you can quote this note from your own instance. Search https://metalhead.club/users/mariusor/statuses/114403853582818101 on your instance and quote it. (Note that quoting is not supported in Mastodon.)
