Bintray offers secure, private repositories that provide fine-grained access control over your packages. Manage Bintray users through organizations, teams and permissions. Give external users time-limited download privileges to specific files using signed URLs. For even greater control, manage entitlements and access keys that can even integrate with your existing authentication mechanisms. Bintray’s security capabilities give you the freedom to give access at any level - from a complete repository down to a specific file.
