First, you have to open your config/middleware.py. It’s necessary to import AuthBasicHandler: from paste.auth.basic import AuthBasicHandler.

Next step is find ‘app = PylonsApp()‘. Change this line to: ap = PylonsApp() and add after: app = AuthBasicHandler(ap, “My realm”, authfunc). Of course you need to create auth function, for example:

def authfunc(environ, username, password):
    if username == 'myusername' and password == 'mypassword':
        return True
    else:
        return False

Restart your application environment.

That’s it
