What is SPA Auth?

Secure Password Authentication (SPA) is a proprietary Microsoft protocol used to authenticate Microsoft email clients with an electronic mail server when using the Simple Mail Transfer Protocol (SMTP), Post Office Protocol (POP), or Internet Message Access Protocol (IMAP).

Which mechanism is used to authenticate a user in a spa?

Token. The user sends a username and password, and in exchange gets a token that can be used to authenticate requests. This is marginally more secure than HTTP Basic Auth, because as soon as the username/password transaction is complete you can discard the sensitive data.

What is the difference between the authentication and authorization?

What is SPA API?

What is authorization code grant?

4.1. The authorization code is a temporary code that the client will exchange for an access token. The code itself is obtained from the authorization server where the user gets a chance to see what the information the client is requesting, and approve or deny the request.

Why OAuth is secure?

It’s the most secure flow because you can authenticate the client to redeem the authorization grant, and tokens are never passed through a user-agent. There’s not just Implicit and Authorization Code flows, there are additional flows you can do with OAuth.

How is authentication done in Web API?

Web API assumes that authentication happens in the host. For web-hosting, the host is IIS, which uses HTTP modules for authentication. You can configure your project to use any of the authentication modules built in to IIS or ASP.NET, or write your own HTTP module to perform custom authentication.

Why is OAuth better than Basic Authentication?

While the OAuth 2 “password” grant type is a more complex interaction than Basic authentication, the implementation of access tokens is worth it. Managing an API program without access tokens can provide you with less control, and there is zero chance of implementing an access token strategy with Basic authentication.
