Security and privacy are key in instant messaging, it is not for nothing that we are used to communicating too much private data through these platforms. Due to this, companies like WhatsApp have integrated systems such as end-to-end encryption by default, also the encryption of backup copies or an account access code that will appear from time to time. Although WhatsApp has had serious doubts about its privacy, continues to develop new ways to secure it. As one that is already testing.
Authorize the change of mobile even after the six-digit code
Currently, WhatsApp only warns that the number is being registered on another phone
Currently, the process that requires changing a WhatsApp account from a mobile involves the following steps:
- Install the application on the new mobile.
- Start the new app and enter the phone number associated with the WhatsApp account.
- In the old mobile appears the message of “WhatsApp registration code requested“. The six-digit code with which the change of device is authorized is sent to the phone that has the SIM.
- Simply enter the code in the WhatsApp that is starting (new mobile) so that the account changes phones; deactivating in the previous mobile.
With the current exchange process, if someone has access to the six-digit code (either because of a SIM Swapping or because they have scammed the account owner) will get control of WhatsApp number. And it is right here where the company is going to influence with its latest change, still in testing.
As WaBetaInfo discovered, WhatsApp will force the user to accept the change to the new phone from the previous mobile. This way you will not only know that someone is trying to take your account, you can also prevent it by simply denying permission. And it will not matter that the “thief” has obtained the six-digit code that WhatsApp sends with the SMS, you will not be able to access the account unless the change is accepted on the old phone (the one with the operating account).

This little novelty at the start of WhatsApp is a great barrier against account theft. It is true that it is not infallible since, equally, thieves can get the user if they have access to the SIM and the old mobilebut it does significantly reduce the risks.
Now we only need to know when it will end up being implemented in the applications: as shown in WaBetaInfo, the function is still at the beginning of its development.
