Best Multi-Factor Authentication (MFA) Apps for Blazor

Identity is a core element of software architecture, and too often, solutions force enterprises to choose between control and commercial readiness. You end up locked into rigid platforms or forced to sacrifice security for flexibility. Duende IdentityServer eliminates this compromise. We are a secure, standards-compliant identity infrastructure software solution, built natively for .NET by industry leaders and pioneers in security standards, including OpenID Connect, OAuth 2.0, Backend for Frontend (BFF), and FAPI. We give developers deep extensibility by design—full control over the UI, business logic, and hosting—combined with the commercial and legal clarity and predictable pricing that enterprises in highly regulated industries demand, like financial services and healthcare. If you need to embed compliant, composable identity without sacrificing control or maturity, Duende is the proven secure identity standard. We bring the craft to identity, so you can focus on yours.
