• receive, from a server of a website, data for a hypertext markup language (HTML), in response to accessing to the website,
• detect information indicating a completely automated Turing test to tell computers and humans apart (CAPTCHA) service by parsing the data received from the server of the web site,
• in response to the detection of the CAPTCHA service, determine, based on the detected information for the CAPTCHA service, whether the CAPTCHA service is provided in a form of audio data or the CAPTCHA service is provided in a form of image data,
• in response to the determination that the CAPTCHA service is provided in the form of the audio data, reproduce the audio data via a speaker of the electronic device to authenticate a user of the electronic device,
• in response to the determination that the CAPTCHA service is provided in the form of the image data, transmit, by the electronic device, the image data to another user operating an external electronic device other than the server of the website for completion of the CAPTCHA, and
• after transmitting the image data to the external electronic device, receive, from the external electronic device, data generated by the another user of the external electronic device, the generated data for solving the CAPTCHA provided in the form of the image data.
