In your config.php you have to define constant YOURLS_PRIVATE. It can be one of these two lines:

// Private :
define( 'YOURLS_PRIVATE', true );
// Or public :
define( 'YOURLS_PRIVATE', false );

Private

Setting to define( 'YOURLS_PRIVATE', true ); (default setting) will make your admin area (http://sho.rt/admin/) protected by a login/password form.

Public

Setting to define( 'YOURLS_PRIVATE', false ); will make your admin area free to access to anyone with the URL. Use this only if you're running a test setup, or for a setup shared by colleagues on a private intranet, for instance.

Also, since there is no login/password needed, there will be no Secret Token on the Tools page for the PasswordlessAPI.

Private + Public Interface

If you want to run your own little bitly, you want to :

• set your install to private : define( 'YOURLS_PRIVATE', true );
• install a public interface in the root directory. There's a sample one provided in the package (see sample-public-front-page.php.txt)
