options = webdriver.ChromeOptions()
options.add_argument('headless')
    
options.add_argument("--start-maximized") # add
options.add_argument("--window-size=1920,1080") # add
    
dv = webdriver.Chrome(path, options=options)

selenium 로그인이 안될때 

option = webdriver.ChromeOptions()
option.add_argument('user-agent=Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/35.0.1916.47 Safari/537.36')

그래도 안될때 

option.add_argument('--disable-blink-features=AutomationControlled')
option.add_argument("--disable-extensions")
option.add_experimental_option('useAutomationExtension', False)
option.add_experimental_option("excludeSwitches", ["enable-automation"])

아래꺼 넣으니까 된다 

전체

option = webdriver.ChromeOptions()
option.add_argument('--no-sandbox')
option.add_argument("disable-gpu")
option.add_argument("--lang=ko_KR")
option.add_argument('user-agent=Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/35.0.1916.47 Safari/537.36')
option.add_argument('--disable-blink-features=AutomationControlled')
option.add_argument("--disable-extensions")
option.add_experimental_option('useAutomationExtension', False)
option.add_experimental_option("excludeSwitches", ["enable-automation"])
driver = webdriver.Chrome(path, options=option)
driver.get("https://naver.com")

headers = {'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/35.0.1916.47 Safari/537.36'}

res = requests.get(url,headers=headers)

요렇게 헤더를 넣는다
