      lharolds Signal is the gold standard for messaging. Hyper-secure, privacy focused and best of breed - funded by Brian Acton after he cashed in from the sale of WhatsApp to Facebook. Likely because he felt bad for selling his product to a company where he knew that they would compromise on privacy and security.

      Functionally Signal is very similar to WhatsApp. What I prefer about Signal is its respect for its users and focus and commitment to transparency and privacy. WhatsApp, while E2E encrypted, still collects an enormous amount of metadata about its users for commercial purposes.

    2. Element is a secure collaboration and messaging app based on the Matrix protocol. It’s decentralised to deliver digital sovereignty, and based on an open standard for easy connections and interoperability. It is end-to-end encrypted by default.

      Element is end-to-end encrypted (including groups unlike Telegram) and does not require a phone number (which is personally identifiable information. Signal requires it). Element is very simple to use for the average person yet very useful for the advanced one (a personal server can be deployed). It is also libre/free (as in freedom) and fully open-source, based on a libre/free protocol (matrix.org).

      It is open source, encrypted (end to end), the server is also open source, which means that you or your university could run the server for you. This last point makes it very solid in the long run (like email survived because the protocol was federated).

      This service is an alternative to Slack & MS Teams, but too technical and not designed for individual use.

      More Privacy oriented, more secure, but best of all OpenSource. Unfortunately it ain't free (as in money but free as in freedom).

      Basically Signal on steroids. Also, open source and doesn't ask for your phone number, allows creation of throwaway accounts as well as basic group conversation functionality. Perfect.

      More a competition for skype then whatsapp. however there's nothing you can do on whatsapp that you cannot do on wire. its trustworthy, has phone calls, can be used on PC/Mac as well.. registration with phonenumber is optional, which is nice.

      Tox vs WhatsApp opinions
      Almost everyone thinks Tox is a great alternative to WhatsApp.
      Focused on security messages are encrypted and it is Open Source. Like whatsapp, you can send files, groups chats and video messaging. Skype is more popular with normies, but Tox has all the bells and whistles that whatsapp did.

      MetaPixel_ Secure and high quality peer-to-peer communication, audio and video group calls, and unlimited file transfers. The only disadvantage compared to alternatives is that you can only successfully communicate if both peers are online, but that is part of the nature of the protocol and thus safety is prioritized.

      Works well on desktop but not mobile like Whatsapp. Only mobile apps are experimental and not user friendly.

      Secure, non-US based and you're the Customer, not the product. They really take care of your privacy!

      Threema is a great whatapp alternative. Just as easy to use as whatsapp, but (hopefully) more secure and non US based. However, just like whatsapp, it is an app only and lacks a client for PC.... :(

      duco It's also end to end encryped but not run by a US company that could force the company to give out data. It has a better data protection then signal as no mobile phone number is required. The address book can be uploaded but doesn't has to. Also you can scan the IDs of others as QR-Code and three dots display very prominent for each contact how secure it is.
