How it works:
Many legacy apps use headers to authenticate users. Azure AD B2C uses token-based authentication. Grit App Proxy allows you to migrate your legacy apps to Azure AD B2C without changing any code. The proxy will authenticate users with Azure AD B2C. Once authenticated, the proxy will add the appropriate headers to the request and forward it to your legacy app. The users will be authenticated and your legacy app will continue to function as it did before.
