I'm exploring a new idea called FediOTP (codename): an authentication system that uses #ActivityPub DMs to deliver one-time passwords, allowing any #fediverse account to authenticate with web services. Unlike current solutions that rely on specific APIs (#Mastodon, #Misskey), this would work with any ActivityPub-compatible server, increasing interoperability across the fediverse. Would love to hear your thoughts on potential challenges or use cases for this approach.
@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
If you have a fediverse account, you can quote this note from your own instance. Search https://mitra.social/objects/019671ae-939c-9544-55bf-2e34f1a9eca5 on your instance and quote it. (Note that quoting is not supported in Mastodon.)
