				"description": "Prior to authentication, you must complete a captcha. Go to https://hr-humblebundle.appspot.com/user/captcha, then paste the following code in the JS console:\n```\nwindow.Android = {\n    setCaptchaResponse: function(challenge, response) {\n        console.log(response);\n    }\n}\n```\nNow complete the captcha. When you click Submit, a big long nonsense string will appear in the JS console. Copy this and add it to your Postman environment as a variable named 'recaptcha_response'.\n\nIf you use two-factor authentication, you will also need to set your 'authy\\_token' environment variable to the current token. If you prefer SMS to the authenticator app, leave the 'authy\\_token' blank and change the send\\_sms value in the request body to \"true\", then submit the request. You'll receive your token via SMS, then you can fill it in as 'authy\\_token' and redo the request to complete the login."
