Hello! It seems like you're encountering an issue with changing your Facebook password because you're being prompted for a WhatsApp code that you're not receiving. Here are a few steps you can try to resolve this issue:
1. Check your spam folder: Sometimes, verification codes can end up in the spam folder of your email account. Make sure to check there if you haven't already.
2. Resend the code: If you're given the option to resend the code, try that to see if it arrives the second time.
3. Contact WhatsApp support: If you're consistently not receiving the code, you may want to reach out to WhatsApp support for assistance. They may be able to help troubleshoot the issue on their end.
4. Check your phone number: Make sure the phone number associated with your Facebook and WhatsApp accounts is correct and up to date. Incorrect phone numbers can cause issues with receiving verification codes.
5. Clear cache and data: Sometimes, clearing the cache and data of the WhatsApp app can resolve issues with receiving verification codes. You can do this in the settings of your device.
If none of these steps work, you may need to reach out to Facebook support for further assistance with changing your password without needing a WhatsApp code.
