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).

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).

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.

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.

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.

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.

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.... :(
