Passwords are the weakest link — and .NET 10 just made it easier to remove them.

With built-in support for passkeys and WebAuthn, you can authenticate users securely without storing a single password.

.NET 10 introduces native passwordless authentication APIs through Microsoft.AspNetCore.Identity and WebAuthn integration.

Developers can now use FIDO2 keys, Windows Hello, or biometrics with minimal setup.

This means stronger security, smoother UX, and fewer support calls for “forgot password.”

𝗖𝗼𝗱𝗲 𝗘𝘅𝗮𝗺𝗽𝗹𝗲:

builder.Services.AddAuthentication()
.AddWebAuthn(options => options.RelyingPartyName = "MyApp");

await signInManager.PasswordlessSignInAsync(user);

(That’s it — no passwords, just identity.)

Would you trust a fully passwordless login in your next .NET project — or do you still keep a fallback password?
