Hey krishna1502,

If we understand correctly, you're not receiving your verification code for two-factor authentication. If that's right, take a look at the following guide for the ways to receive a verification code: Get a verification code and sign in with two-factor authentication - Apple Support

If that's not the case, let us know more about the verification code you're not receiving. For the issue you're having with WhatsApp not downloading, these steps should help to resolve that issue: If you can’t download or update apps on your iPhone or iPad - Apple Support
