Multi-Factor Authentication (MFA) Software Resources

I am using the AWS IP range JSON file here, https://ip-ranges.amazonaws.com/ip-ranges.json, to associate the EC2 eu-west-1 region with a range of IP addresses.

When building B2B SaaS products, organizations often have to choose between strong multi-tenant identity systems and a smooth user experience. Features like tenant isolation, detailed authorization, and enterprise SSO usually need a lot of custom work, and things get more complicated as company structures and permission rules expand. Teams often find that some platforms manage authorization well but make the user journey harder, while others focus on user experience but lack advanced enterprise identity features.

Organizations evaluating CIAM platforms for non-technical stakeholders often struggle with solutions that require deep engineering involvement to configure and modify authentication flows. Teams need platforms where product managers, designers, and security stakeholders can review, iterate, and collaborate on user journeys without waiting on developer cycles. The ability to visually design complex flows, including MFA, passwordless login, and social authentication, while maintaining clean developer APIs is a rare but critical combination for fast-moving teams.
