Signal or Telegram: Which app is more secure

WhatsApp has decided to share its users’ data with Facebook. For this, the company is going to introduce new Terms and Privacy Policy. If users don’t agree with this new Terms and Privacy policy, they may face account deletion. This has prompted them to look for other options.  

Signal 

Signal owns the Open Whisper System, which WhatsApp has been using for end-to-end encryption of conversation on the messaging app. Open Whisper System ensures automatic end-to-end encryption of conversations on the platform.

The encryption keys are stored on the phones, laptops, and desktops of the users, which minimises the risk of compromising personal data. Users get notifications when any of their contacts’ encryption key changes. 

By using a passcode or scanning a QR code, users can verify each other. Besides this, the app doesn’t keep users’ metadata, logs, and other details. Apart from this, the app doesn’t keep any record of your contacts, conversations, locations, profile, name, group memberships, and others. 

The conversations taking place on this app requires users’ actions for back up, the app doesn’t offer back up to users’ conversations by itself. Users can choose a secure cloud for backing up their conversations on the platform. 

The App also has a setting, customizing which enables users to receive sealed messages from those who are not in their contact. This setting keeps users’ IP secure from unknown contacts.  

Telegram

Telegram has its own end-to-end encryption system that is known as MTProto.  The default cloud messaging system of this app is not end-to-end encrypted. The app stores conversions on its servers and back them up to a cloud. This transpires a meaning that the app can access your messages.

The app, however, offers a secret chat option that enables its users to get the advantage of encryption. Using secret chat, user can secure their messages on the platform from all expect the desired receiver of their messages.  Telegram keeps your address book on its servers and doesn’t entirely encrypt all metadata.
