Instagram introduced a new security feature dubbed Security Checkup to help users to recover their accounts that have been compromised. Feature aims to keep accounts safe and help users re-gain access to accounts. Users will have to perform a series of actions, such as reviewing profile information, checking recent login activity, and updating contact details (i.e. email address, phone number) The company would allow users to use their WhatsApp numbers to authenticate their accounts, but the feature will be available only in selected countries.”]
