When talking about messaging platforms, there are several different options available. At the same time, WhatsApp constantly secures a top position in the list. This is one of the best messaging apps, and credit goes to its robust set of features, enhanced security, and convenience to use. Additionally, things will go be great in the coming days. Since the meta company will be intended to bring improvements to the app’s security.
Eventually, it’s a fact known by all WhatsApp users that switching from one device to another is not easy. Talking about the companion mode then that would certainly be a thing of the past. For those who want to keep things as secure as they can, intended to prevent them from being commandeered switches without authorization. As per the WhatsApp blog, this is where the company’s new ‘Account Protect’ initiative comes into play. Since it requires authorization and verification on the old device before the account is transferred to a new handset or tablet.
Talking about another method in order to keep the users and their accounts protected is Device Verification. WhatsApp is known for its end-to-end encryption. Also, there are times when malware can interfere with such a secure environment. While these infections can interfere with the way the app functions. This comprises sending out messages without the user’s permission or knowledge.
New parameters to prevent unauthorized third-party access
At the same time, although its authentication keys are safe, also there are occurrences whereby some wretch apps can steal the information. For instance, unauthorized third party, WhatsApp clients. Therefore, device verification will use three new parameters in order to prevent this kind of activity from occurring in the future. Simultaneously prevent malware from stealing the authorization key, while connecting from an outside device. These three new parameters are:
- A security token that’s stored on the user’s device.
- A nonce is used to identify if a client is connecting to retrieve a message from the WhatsApp server.
- An authentication challenge that is used to asynchronously ping the users` devices.
Auditable Key Directory approach
WhatsApp will introduce an Auditable Key Directory (AKD). It enables users to conveniently and instantly validate a code. The approach and its component are described below:
- The server (WhatsApp) maintains an append-only AKD of public keys mapped to user accounts.
- A third-party audit record, wherein any change in the server directory is recorded in a publicly available, privacy-preserving audit record for anyone to verify.
In contrast, this new method is secure and faster comparatively. Whereas, WhatsApp state that conventional security code verification will be the best option for users if they don’t require a feature that relies on its servers.
