-#### Basic authentication
+Choose between [writeKey authentication](#writeKey-authentication) and [OAuth](#oauth) to authenticate requests. 
 
+#### writeKey authentication
 Authenticate to the Tracking API by sending your project's **Write Key** along with a request.
-Authentication uses HTTP Basic Auth, which involves a `username:password` that is base64 encoded and prepended with the string `Basic`.
-
-In practice that means taking a Segment source **Write Key**,`'abc123'`, as the username, adding a colon, and then the password field is left empty. After base64 encoding `'abc123:'` becomes `'YWJjMTIzOg=='`; and this is passed in the authorization header like so: `'Authorization: Basic YWJjMTIzOg=='`.
-
-> info ""
-> Include a colon before encoding. While encoding the write key without a colon might work due to backward compatibility, this won't always be the case.  
+The authentication writeKey should be snet as part of the body of the request. This will be encrypted over https.
 
 #### OAuth
 [Obtain the access token](/docs/connections/oauth/) from the Authorization Server specific to the region.
