How to Choose a Secure Messaging App

Selecting a secure messaging application is vital to maintain your privacy and avoid having your communications unsafely exposed. Here are some factors to consider when you choose your secure messaging application:

1. End-to-End Encryption: The application should provide end-to-end encryption (E2EE) to assure that only the intended recipients can decrypt (and then read) the messages. The service provider is essentially “blind” to the contents of your messages.

2. Open Source: Open-source applications allow their source code to be publicly visible, and reviewed by security experts. This transparency provides some degree of comfort that the application does not have hidden vulnerabilities or backdoors.

3. Security Audits: If a messaging application has done any security audits by independent third-party organizations, check it out. The more audits there are, the more likely the potential security issues will be identified and fixed.

4. User Authentication: The application should have a secure user authentication policy – ideally, the application should provide options that include two-factor authentication (2FA).

5. Message Retention Policies: Before you subscribe to a messaging application, determine what its message retention policies are. Some applications will retain messages for some time and others retain messages indefinitely, depending on the policies. You need to find out which application you prefer because of data retention policies.

6. Metadata Privacy: Also consider the high level of privacy for metadata. Metadata is the information connected to your communication, such as who is speaking to whom, when they are communicating, and for what duration. There are apps that limit the amount of information collected and kept as metadata.

7. Cross Platform: Select a messaging platform that will run on more than one operating system (such as iOS, Android, Windows, macOS, etc.). Many of your contacts may be using different devices than you.

8. Features: In addition to privacy and security features, you should consider whether the app provides additional user privacy options. For example, some apps provide self-destruct messaging, meaning that the sender can select an expiration time for their message. Other apps may provide the option to turn off read receipts.

9. Community and Registry Building Trust: When choosing a messaging app, you should also consider the overall respect and use of the app by others. Apps with an established user community can often identify security vulnerabilities faster than others that have a smaller stressful and dynamic user community. Looking over user review and testimonials can help with understanding user satisfaction with the app.

10. Legal Basics – Compliance: It is best practice to also examine the extent to which the messaging app has complied with other legal requirements applicable to your local jurisdiction. A level of compliance or adherence, such as that required under GDPR, can show forethought to user privacy.

11. Updates to App: Developers will regularly use updates as a way to establish user credibility, and consistently apply updates to their app accordingly. The prevalence and reputation of your community or registry identity can be reduced with meaningful updates, addressing web vulnerabilities.
