description: |
  **Session** is an encrypted instant messenger that uses three random [service nodes](https://getsession.org/blog/onion-requests-session-new-message-routing-solution) to route messages anonymously on the [Oxen Network](https://oxen.io).

  Session allows for E2EE in one-to-one or closed rooms that allow up to 100 members.

  Open rooms have no restriction on the number of members, but anyone can join.

  #### Notes
  Session does [not](https://getsession.org/blog/session-protocol-technical-information) support forward secrecy. The key pair for each conversation is not rotated.

  #### Technical information
  Session was independently [audited](https://getsession.org/session-code-audit/) in 2020. The protocol is described in a [whitepaper](https://arxiv.org/abs/2002.04609).
