Statement on security

At its core, OpenProject is an open-source software that is developed and published on GitHub. Every change to the OpenProject code base ends up in an open repository accessible to everyone. This results in a transparent software where every commit can be traced back to the contributor.

Automated tests and manual code reviews ensure that these contributions are safe for the entire community of OpenProject. These tests encompass the correctness of security and access control features. We have ongoing collaborations with security professionals from to test the OpenProject code base for security exploits.

OpenProject security features


OpenProject administrators can enforce authentication mechanisms and password rules to ensure users choose secure passwords according to current industry standards. Passwords stored by OpenProject are securely stored using salted bcrypt. Alternatively, external authentication providers and protocols (such as LDAP, SAML) can be enforced to avoid using and exposing passwords within OpenProject.

User management and access control

Administrators are provided with fine-grained role-based access control mechanisms to ensure that users are only seeing and accessing the data they are allowed to on an individual project level.

Two-Factor authentication. (Cloud or Enterprise Edition)

Secure your authentication mechanisms with a second factor by TOTP standard (or SMS, depending on your instance) to be entered by users upon logging in. More information.
