  • Identity server 4
    Its deprecated in favor of Duende Identityserver which introduced a license model. Source: 5 months ago
  • How does cookie based authentication work?
    Tokens usually have a lifetime and they are separate from the user's authentication principals like username and password. Unless you are rolling your own form of token provider (not something that would be recommended) the token creation is handled for you. Take a look at https://identityserver4.readthedocs.io/en/latest/ or if your organization makes under 1M in income a year the free version of what Identity... Source: over 1 year ago

  • Bluesky partners with Namecheap to power domains as usernames
    Certainly _buying_ domain names to be your identity is new, but OpenID[1] was doing basically that 15 years ago. Add a few meta tags to your website homepage, use that homepage as your "identity" to log in to websites, and they'd up your configured identity provider to do the login & request name/email/whatever else. You weren't locked in to a particular provider, since you logged in as _your_ webpage and could... - Source: Hacker News / 10 months ago
