WhatsApp reportedly planning to notify users about security code changes, here is what it means

WhatsApp is rolling out the multi-device capability for Android and iOS users but due to this a lot of users are being told that their security codes have changed. Wabetainfo, which tracks all the WhatsApp-related updates, noted in a tweet that the messaging app is planning to send notifications about security code changes when the user re-registers the account on a new phone. Every chat has a unique security code and can be used to verify that the messages that you send to your contacts are end-to-end encrypted. “End-to-end encrypted chats between you and one other person have their own security code used to verify that the calls and the messages you send to that chat are end-to-end encrypted. Security codes are just visible versions of the special key shared between you - and don't worry, it's not the actual key itself, that's always kept secret,” WhatsApp said.
