Goals

  • Use OWASP to guide best practice and default configurations.

  • Be more opinionated and ‘batteries’ included by reducing reliance on abandoned projects and bundling in support for common use cases.

  • Follow the Pallets lead on supported versions, documentation standards and any other guidelines for extensions that they come up with.

  • Continue to add newer authentication/authorization standards:

    • ‘Social Login (OAuth)’ integrated (using authlib) (5.1)

    • WebAuthn/Passkey support (5.0)

    • Two-Factor recovery codes (5.0)

    • First-class support for username as identity (4.1)

    • Support for freshness decorator to ensure sensitive operations have new authentication (4.0)

    • Support for email normalization and validation (4.0)

    • Unified signin (username, phone, passwordless) feature (3.4)

    • Two/Multi-Factor authentication supporting SMS, email, authenticator apps (4.0)
