Swagger UI 3.13.0+ provides the preauthorizeBasic method for this purpose. Assuming your API definition includes a security scheme for Basic auth:

swagger: '2.0'
...
securityDefinitions:
  basicAuth:
    type: basic

security:
  - basicAuth: []

you can specify the default username and password for Basic auth like so:

// index.html

const ui = SwaggerUIBundle({
  url: "https://my.api.com/swagger.yaml",
  ...
  onComplete: function() {
    // "basicAuth" is the key name of the security scheme in securityDefinitions
    ui.preauthorizeBasic("basicAuth", "username", "password");
  }
})

Now, if you click the "Authorize" button in Swagger UI, you will see that the username and password are pre-filled.

Original answer (for Swagger UI 3.1.6—3.12.1):

You can add the requestInterceptor to your Swagger UI's index.html file in order to add the Authorization header automatically to "try it out" requests. requestInterceptor is supported in Swagger UI 3.1.6 and later.

// index.html

const ui = SwaggerUIBundle({
  url: "http://my.api.com/swagger.yaml",
  ...
  requestInterceptor: (req) => {
    if (! req.loadSpec) {
      // Add the header to "try it out" calls but not spec fetches
      var token = btoa("username" + ":" + "password");
      req.headers.Authorization = "Basic " + token;
    }
    return req;
  }
})
