The WhatsApp OTP option is a quicker method for receiving OTP. To use it, you must enable 2FA via the SMS option.
Here's how to locate the WhatsApp OTP option.
On the website:
Log into your account.
After signing in, wait for the "Resend code time" to elapse, then click "Resend code to WhatsApp."
An OTP code will be sent to your WhatsApp. Enter the code to log into your account.
On mobile:

Make sure the phone number registered on the app is the same as the one linked to your WhatsApp account.
