Our WhatsApp group administrator has lost his phone

Question

Our group administrator lost his phone, but now has a new one with a new number. How can we change the administrator so that he can rejoin the group with the new number?

Answer 1

Probably not, now that your account is gone. PS: Whatsapp's approach to easy registering (using the phone no. as id and auth) is fundamentally broken, they have (or at least recently had) very bad security problems and other nasty workarounds/limitations: whatsapp.com/faq/en/general/20971798 (Also, please do not swap SIM cards or phones frequently, or you will no longer be able to pass the verification process.
