Signal’s app and website have stopped working in mainland China without the use of a VPN. Cyber authorities of the countries have been very strict in the recent past. They were restricting the access of apps, media outlets and social media sites by banning them in the country. The app, however, was still available on Apple’s China app store. Both the website and app were reportedly working normally in Hong Kong.
Signal – a WhatsApp rival – has now taken on to Zoom as it launches its one-on-one E2EE VC feature for desktop. The COVID-19 pandemic has boosted the demand for VC platforms and Zoom’s earlier vulnerabilities highlighted its weaker control over users’ security. This gives Signal a competitive edge over Zoom. Further, the app also allows messages from people who are not in users’ contact lists in the form of ‘message requests’ – a feature that WhatsApp lacks.
