What are the benefits of using passkeys in iframes?

Using passkeys within iframes provides significant benefits for both user experience and security, especially in scenarios involving cross-domain integrations:

• No redirects or pop-ups:
  Users can authenticate directly within embedded content, leading to a seamless and interruption-free user journey. This streamlined process enhances conversion rates, especially critical in checkout and login flows.
• Consistent UX across domains:
  Passkeys embedded in iframes ensure users experience uniform authentication interfaces across different sections of a website or even different websites using the same authentication provider.

• Phishing-resistant authentication:
  Passkeys provide strong, phishing-resistant user authentication within a secure iframe context, significantly reducing vulnerability to common attacks.
• Secure transactions and payments:
  Particularly beneficial in payment flows, passkeys embedded in cross-origin iframes enable secure, frictionless authentication without exposing credentials outside the secured iframe environment.

• Passkeys within cross-origin iframes facilitate federated identity scenarios (e.g. payment), allowing secure and effortless authentication across multiple related domains using a single user account. This is essential for multinational organizations or businesses operating multiple domains.

In short, embedding passkeys within iframes combines strong security with exceptional UX, making it ideal for modern web applications, payment gateways, and federated identity solutions.
