The decentralized social project Bluesky has launched a short-term verification solution called App Passwords

ChainCatcher message, a short-term authentication solution App Passwords released by the Twitter-funded decentralized social project Bluesky, allows users to try out new clients without fully trusting their passwords. In the long term, Bluesky plans to implement SSO (Single Sign-On) with scoped permissions.

Bluesky stated that its core development team is currently focused on completing the AT protocol, with priorities in the coming months being domain names as usernames and account portability, composable moderation and reputation systems, algorithm selection, and custom feeds. (Source link)
