The equivalent Java configuration is: SecurityFilterChain filterChain(HttpSecurity http) The simplest possible solution to implement basic HTTP authentication is to use “ http-basic” tag in spring security configuration file like this. The security-related packages and classes are part of the spring security module so let us start with importing the module, first. The client sends HTTP requests with the Authorization header that contains the word Basic word followed by a space and a base64-encoded string username:password.įor example, to authorize as user / password the client would send: Authorization: Basic dXNlcjpwYXNzd29yZA= However, basic authentication transmits the password as plain text so it should only really be used over an encrypted transport layer such as HTTPS.īecause a basic authentication header has to be sent with each HTTP request, the web browser needs to cache the credentials for a reasonable period to avoid constant prompting the user for the username and password. It’s quite common to use it in combination with form-based authentication where an application is used through both a browser-based user interface and as a webservice. What is Basic Auth?īasic authentication is often used with stateless clients who pass their credentials on each request. Learn to configure basic authentication in an application secured with Spring security.
