Editing Tencent QQ (section)

==Security==

On March 6, 2015, QQ scored 2 out of 7 points on the [[Electronic Frontier Foundation]]'s secure messaging scorecard. It received points for having communications encrypted in transit and for having a recent independent security audit. It lost points because communications are not [[End-to-end encryption|end-to-end encrypted]], users can not verify contacts' identities, past messages are not secure if the encryption keys are stolen (i.e. the service does not provide [[forward secrecy]]), the code is not open to independent review (i.e. the code is not [[Open-source software|open-source]]), and the security design is not properly documented.<ref>{{cite web|url=https://www.eff.org/secure-messaging-scorecard|publisher=Electronic Frontier Foundation|title=Secure Messaging Scorecard.
