Encrypted messaging apps are experiencing a resurgence, with Vitalik Buterin advocating for more secure messaging that doesn’t rely on phone numbers or KYC. Session, a decentralized messenger, combines E2E encryption with decentralized servers to enhance privacy. Forty-three percent of public WiFi users have experienced data breaches, highlighting the importance of secure messaging.

Session stores messages using public key identities and onion routing for secure transmission. Messages are stored in encrypted swarms for asynchronous delivery and are deleted after two weeks. The app also maintains a local database for long-term chat history, allowing users to access messages months or years later.

Session offers Fast Mode notifications for timely alerts but exposes IP addresses to Apple’s push server. Slow Mode provides more privacy but may result in delayed notifications. The app’s governance has shifted to the Session Technology Foundation, ensuring transparency in handling government requests for information.

Concerns about quantum resistance and calls remain, with Session working on a major protocol redesign for enhanced security. Voice and video calls are available but still in beta, exposing IP addresses to peers and Session servers. Decentralization offers greater privacy but does not eliminate all potential risks associated with messaging apps.

Overall, decentralized messaging like Session offers increased privacy and security, but users must be aware of the limitations. While metadata minimization and post-quantum upgrades are in development, users should take precautions such as using Slow Mode notifications and disabling calls if IP address exposure is a concern. Session is one of many projects working to enhance secure messaging in the face of evolving threats.
