How to click on 2FA 'Duo Push Button' using Selenium in python

Question

I am trying to click on a 2FA 'Send me a push' button, however none of my previous attempts have succeeded

def launch_login():
    #open login web page

    chrome_options = Options()
    chrome_options.add_experimental_option("detach", True)
    driver = webdriver.Chrome(service=Service(ChromeDriverManager().install()))
    driver.get("http://my.csus.edu")
    #enter login

    driver.find_element(By.XPATH, "//input[@id='username']").send_keys("xxxxxxxx")
    driver.find_element(By.XPATH, "//input[@id='password']").send_keys("xxxxxxxx")
    login = driver.find_element(By.XPATH, "//button[contains(text(),'Login')]")
    login.click()
    #click duo push button

    driver.find_element(By.XPATH, "//button[starts-with(@class, 'positive auth-button') and contains(., 'Send Me a Push')]").click()

    return driver
driver = launch_csus()

This is error I am receiving

selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: {"method":"xpath","selector":"//button[starts-with(@class, 'positive auth-button') and contains(., 'Send Me a Push')]"}
  (Session info: chrome=101.0.4951.41)

I am still pretty new to selenium and am learning as I go. Is the button a special type of button that behaves in a certain way? Is there a specific way to access the button?

The button with the text as Send Me a Push is within an <iframe>

duo_iframe

Solution

So to click on Send Me a Push you have to:

Induce WebDriverWait for the desired frame to be available and switch to it.
Induce WebDriverWait for the desired element to be clickable.

You can use either of the following locator strategies:

driver.get("http://my.csus.edu")
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//input[@id='username']"))).send_keys("xxxxxxx")
driver.find_element(By.XPATH, "//input[@id='password']").send_keys("xxxxxxxx")
driver.find_element(By.XPATH, "//button[contains(text(),'Login')]").click()
WebDriverWait(driver, 20).until(EC.frame_to_be_available_and_switch_to_it((By.XPATH,"//iframe[@id='duo_iframe']")))
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//button[normalize-space()='Send Me a Push']"))).click()

Note: You have to add the following imports:

from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
