How to continue automation after entering OTP manually using Selenium and Java

To continue automation after entering OTP manually using Selenium would be to use the Scanner class as follows:

driver.findElement(By.xpath("xpath_mobile_field")).sendKeys("9818414799");
scanner_user = new Scanner(System.in);
System.out.println("Enter the OTP: ");
String user = scanner_user.nextLine();
driver.findElement(By.xpath("xpath_otp_field")).sendKeys(user);

You can find a couple of relevant detailed discussions in:

• Get user input from IDE/Console in selenium webderiver

You don't need to enter that manually, you can use someone's otp generator library, like pyotp in python.

import pyotp
totp = pyotp.TOTP('HASHXXXXXXXXXXXXXXXXXXXXXXXXXXXXX')
ida2f = totp.now()

for java do you have https://github.com/BastiaanJansen/otp-java

To resolve the OTP, you generally need to select the "iframe" first, for example in python.

                            try:
                                iframe = driver.find_element(By.XPATH, '//*[@id="xxxxxOTP"]')
                                driver.switch_to.frame(iframe)

                                iKeys = 0
                                for strs in ida2f:
                                    iKeys = iKeys + 1
                                    driver.find_element(By.XPATH, f'//*[@id="xxxx-html"]/body/div[2]/div[1]/div/div/div/fieldset/div/input[{iKeys}]').click()
                                    time.sleep(0.1)
                                    driver.find_element(By.XPATH, f'//*[@id="xxxx-html"]/body/div[2]/div[1]/div/div/div/fieldset/div/input[{iKeys}]').send_keys(strs)
                                    time.sleep(0.1)

                                driver.switch_to.default_content()
                                time.sleep(3)
                            except:
                                continue

To be reliable, I like to send key by key, and remember about the iframe, it is very important.

For example (java):

driver.switchTo().frame("xxxxxxx");

And remember go to default frame after:

switchTo().defaultContent();

try:
    iframe = driver.find_element(By.XPATH, '//*[@id="xxxxxOTP"]')
    driver.switch_to.frame(iframe)

    iKeys = 0
    for strs in ida2f:
        iKeys = iKeys + 1
        driver.find_element(By.XPATH, f'//*[@id="xxxx-html"]/body/div[2]/div[1]/div/div/div/fieldset/div/input[{iKeys}]').click()
        time.sleep(0.1)
        driver.find_element(By.XPATH, f'//*[@id="xxxx-html"]/body/div[2]/div[1]/div/div/div/fieldset/div/input[{iKeys}]').send_keys(strs)
        time.sleep(0.1)

        driver.switch_to.default_content()
        time.sleep(3)
except:
    continue
