Today privacyIDEA 2.21 was released. Read about it on the privacyIDEA project page.
With privacyIDEA 2.21 it will be possible to enroll smartphone based tokens in a more secure manner and mitigate the threat of simply copying the QR code of the enrolled token. NetKnights still runs a beta test of a new smartphone app. You are welcome to join the beta test!
Also there are enhancements in the event handlers, the rotating of the audit log and the customization of the UI.
The version 2.21 is available via the Ubuntu repositories for 16.04LTS and 14.04LTS and the python package index as a community version.
