Top 5 authentication solutions for secure Flask apps in 2026
Blog post from WorkOS
Authentication is essential for Flask applications, and developers can leverage Flask's flexibility and rich extension ecosystem to tailor authentication solutions to their specific needs. The guide explores five top authentication solutions for Flask apps in 2026, each suited to different requirements ranging from enterprise platforms like WorkOS to popular extensions like Flask-Login and Flask-Security-Too. WorkOS offers a comprehensive suite of enterprise features such as SSO, SCIM provisioning, and multi-tenancy, making it ideal for B2B SaaS platforms looking to cater to enterprise clients. Flask-Login and Flask-Security-Too provide simpler, Flask-native solutions focused on session management and security features without enterprise-level capabilities. Flask-JWT-Extended is best for Flask REST APIs requiring stateless JWT-based authentication, while Supabase Auth offers an integrated platform approach for startups willing to step outside Flask's ecosystem. The choice of authentication solution impacts development velocity, scalability, and enterprise readiness, emphasizing the importance of selecting a provider aligned with future application goals.
