There are a lot of considerations when choosing a secure messaging app. It is important to think about End-to-end encryption, multi-mode messaging, platform synchronization and ease-of-use. Here is a list of popular options. Find one that works for you in order to keep your messaging life safe and secure.
Top Considerations:
- End-to-end encryption is key when if you want your messages to be encrypted so that only the individuals invited into the conversation can read the messages. This keeps ISPs, app makers and the government out of the conversation. 100% from your screen to theirs ensures that anyone trying to snoop on you, will be left empty-handed. This method uses locally stored keys or secret codes and does not allow copies of messages to be stored on external serves.
- Multi-mode communication is the ability to send video, audio as well as texts through an app. This included SMS and MMS.
- Multi-platform support allows you to use and sync messages across mobile, web and desktop platforms. This also allows for you to delete messages on one platform while keeping them securely on another.
