The process is similar in Telegram where you'll need to select “Go to Secret Conversation” from the app's settings. The Wickr Me Android app gets a good score of 4.7 out of 5 stars and has been downloaded over 5 million times. To do so in Messenger, you'll need to tap on the “i” button in the top right corner of an active conversation and then select “Go to Secret Conversation” to create a new end-to-end encrypted conversation.

However, you'll need to do this on a conversation-by-conversation basis. If you're using Facebook Messenger or Telegram to communicate with friends and family over the holidays, CyberNews recommends that you turn on each app's privacy and security settings. App: Signal vs Telegram vs WhatsApp vs iMessage vs Viber vs Wire vs Wickr. CyberNews also found that Briar and Qtox are the only secure messaging apps that use a peer-to-peer (P2P) transport mechanism where there is no server sitting in the middle between the sender and the receiver, enabling messages to go directly from one device to the next. According to the developers, Wickr me differs from hundreds of similar chats. Wickr seems to fail the first criteria for privacy and security oriented software. As a result, messages sent through GSM on 2G and 3G devices are not encrypted. Signal appears better based on that, Wickr's main selling point in comparison would probably be the lack of needing a phone number. One interesting finding from the news outlet's research is the fact that Apple's iMessage (opens in new tab) only uses encryption on HTTPS. With end-to-end encryption, only the sender and the receiver are able to view messages while without it, the messaging app server that sits between the sender and the receiver might be able to read the messages.

Of these apps, Signal, Messenger, WhatsApp and Session all use the Signal protocol for end-to-end encryption (opens in new tab).
