Why this tool?

Yosai is a security framework for Python applications and adds authentication, authorization, and session management capabilities. Features include Role-Based Access Control (RBAC), two-factor authentication, and Time-based One-Time Passwords (TOTP). Besides a focus on the authentication and authorization, Yosai enables an audit trail of all relevant events.
