  • Identity server 4
    Its deprecated in favor of Duende Identityserver which introduced a license model. Source: 7 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
  • ImageSharp leaving the .NET Foundation due to licensing change
    I think Duende (Identity Server) handled the situation pretty well. https://duendesoftware.com/products/identityserver > Standard License Pricing. - Source: Hacker News / over 1 year ago
  • Why is authentication such a sh*t show with .NET 6?
    He's referring to IdentityServer 3/4, which was open sourced, and was not owned by Microsoft. That 3rd party is commercializing their work (and to be fair, it's a lot of work) as https://duendesoftware.com/products/identityserver , and has a different commercial licensing model.

  • How to Set Up 2FA on Your BitStarz Account
    2FA apps such as Google Authenticator and Authy randomly generate a code every minute or so, which is matched to a specific key associated with your login. In essence, this means that whenever a login asks for your 2FA code, it knows which number to expect and will only unlock if that correct number is entered. Source: 7 months ago
  • How can I avoid MFAuthenticator?
    You can also set up the Authy authenticator app on a PC, so you don't have to use a mobile app at all, but use a PC app instead :). Source: 12 months ago
