Account IDs Without Phone Numbers
Session starts with an Account ID rather than a phone number or email address. From the welcome flow, you can create a new identity or choose the option for an existing account, then set a display name that can be changed later. This lowers the friction of starting a separate identity for personal, community, or project conversations while keeping the contact handle distinct from a mobile number.
When you move to another device, the recovery phrase and account-restore process help bring the same identity back. Keep that recovery material private and stored safely, because it is the practical bridge between an installation and an existing Session identity. The result is a clear first step for users who want more control over how contacts find them.
Encrypted Conversations Across Groups
Session combines one-to-one messaging with group conversations built around end-to-end encryption and metadata-aware routing. Messages travel through a decentralized network using layered paths, so the service is designed to reveal less about who is communicating with whom than a conventional phone-number directory. The same account model works for direct chats, groups, and larger community spaces.
Group conversations can bring up to 100 members into a shared thread, while disappearing-message controls help limit how long selected content remains available. These tools fit family updates, volunteer coordination, or private discussions where participants want a practical chat workflow without making a phone number the starting point.
Attachments, Calls, and Message Controls
Beyond text, Session supports sharing voice snippets, photos, and files inside encrypted conversations. The product also documents voice and video calling as a beta capability that can be enabled in settings, giving users a way to choose between asynchronous attachments and a live conversation. Disappearing messages and notification controls add useful choices for how communication appears on a device.
A custom theme can make the interface easier to distinguish across devices, while biometric or passcode protection can add a local lock to the app. Use attachments when a group needs a document or image, send a voice snippet when typing is inconvenient, and treat beta calling as an option whose behavior can depend on network conditions.
Everyday Privacy-Focused Communication
Session is suited to everyday conversations where privacy and flexible identity matter: friends planning a trip, families sharing updates, small teams coordinating a project, or communities organizing around a common interest. The app supports Android alongside desktop and iPhone clients, so a conversation can fit into a mixed-device routine rather than forcing everyone onto one handset.
The useful starting habit is to exchange Account IDs deliberately, select a display name that makes sense for the audience, and choose disappearing messages or notification settings when the situation calls for them. People who need ordinary phone-number discovery may prefer a conventional messenger, but users who value a separate identity and decentralized routing can build a more intentional contact list here.
