Session (software)
Session is a cross-platform end-to-end encrypted instant messaging application. It is developed by The Oxen Project under the non-profit Oxen Privacy Tech Foundation. It uses a decentralized network for transmission. Users can send one-to-one and group messages, which can include files, voice notes, images and videos.[1]

Features
Session does not require a telephone number or email address to create an account.[2] It uses a randomly generated 66-digit alpha-numeric number for user creation/identification. Communication (messages, voice clips, photos, and files) between users is end-to-end encrypted using the Session protocol, a derivative of the Signal protocol. A Tor-like decentralized server network, called Oxen Service Nodes,[3] is used by Session for transmissions. The Oxen Project intends for this network to not store, track, or log the metadata of user messages.[4]
There was an independent review by the third party Quarkslab in 2021 that verified these claims.[5][6]
Limitations
Session does not support two-factor authentication. Underlying protocols are still in a developmental phase.
