v12.0.0 - The one that claims a JSR scope

All SimpleWebAuthn packages are now available for installation from the JavaScript Registry (JSR)! JSR is an "open-source package registry for modern JavaScript and TypeScript" - you can read more about this new package registry and its ESM-centric capabilities here.

All packages in v12.0.0 are functionally identical to v11.0.0! And JSR package hosting is in addition to existing package hosting on NPM. Nothing changes about package installation via npm install. Read on for more information.

Packages

• @simplewebauthn/[email protected]
• @simplewebauthn/[email protected]
• @simplewebauthn/[email protected]

Changes

• [browser] [server] [types] All packages can now be installed from JSR wherever JSR imports are supported (#634)
• [browser] Deno projects using frameworks like Fresh can now import and use @simplewebauthn/browser (#634)

To install from JSR, use npx jsr add @simplewebauthn/... or deno add jsr:@simplewebauthn/... depending on which package manager is available.

Projects using npm for package management:

npx jsr add @simplewebauthn/browser

npx jsr add @simplewebauthn/server

npx jsr add @simplewebauthn/types

Projects using deno for package management:

deno add jsr:@simplewebauthn/browser

deno add jsr:@simplewebauthn/server

deno add jsr:@simplewebauthn/types

Projects using HTTPS modules via deno.land/x:

v12.0.0 officially deprecates importing SimpleWebAuthn from deno.land/x. See Breaking Changes below for refactor guidance.

Breaking Changes

Importing SimpleWebAuthn packages from "https://deno.land/x/simplewebauthn/..." URLs is no longer supported. Please use Deno's native support for JSR imports instead, available in projects running Deno v1.42 and higher.

Before:

import { generateAuthenticationOptions } from 'https://deno.land/x/simplewebauthn/deno/server.ts';

After:

import { generateAuthenticationOptions } from 'jsr:@simplewebauthn/server';

Alternatively, use deno add to install these packages from JSR:

# Deno v1.42 and higher
deno add jsr:@simplewebauthn/server

import { generateAuthenticationOptions } from '@simplewebauthn/server';

v11.0.0 - The one that auto-registers

Say hello to support for automatic passkey registration, support for valid conditional UI <input> elements stashed away in web components, and to the new WebAuthnCredential type that modernizes some logic within.

There are some breaking changes in this release! Please see Breaking Changes below for refactor guidance.

Packages

• @simplewebauthn/[email protected]
• @simplewebauthn/[email protected]
• @simplewebauthn/[email protected]

Changes

• [browser] [server] A new useAutoRegister argument has been added to startRegistration() to support attempts to automatically register passkeys for users who just completed non-passkey auth. verifyRegistrationResponse() has gained a new requireUserPresence option that can be set to false when verifying responses from startRegistration({ useAutoRegister: true, ... }) (#623)
• [browser] A new verifyBrowserAutofillInput argument has been added to startAuthentication() to disable throwing an error when a correctly configured <input> element cannot be found (but perhaps a valid one is present in a web component shadow's DOM) (#621)
• [server] [types] The AuthenticatorDevice type has been renamed to WebAuthnCredential and has had its properties renamed. The return value out of verifyRegistrationResponse() and corresponding inputs into verifyAuthenticationResponse() have been updated accordingly. See Breaking Changes below for refactor guidance (#625)
• [server] verifyRegistrationResponse() now verifies that the authenticator data AAGUID matches the leaf cert's id-fido-gen-ce-aaguid extension AAGUID when it is present (#609)
• [server] TPM attestation verification recognizes the corrected TPM manufacturer identifier for IBM (#610)
• [server] Types for the defunct authenticator extensions uvm and dpk have been removed (#611)

Breaking Changes

[browser] Positional arguments in startRegistration() and startAuthentication() have been replaced by a single object

Property names in the object match the names of the previously-positional arguments. To update existing implementations, wrap existing options in an object with corresponding properties:

Before:

startRegistration(options);
startAuthentication(options, true);

After:

startRegistration({ optionsJSON: options });
startAuthentication({ optionsJSON: options, useBrowserAutofill: true });

[server] [types] The AuthenticatorDevice type has been renamed to WebAuthnCredential

AuthenticatorDevice.credentialID and AuthenticatorDevice.credentialPublicKey have been shortened to WebAuthnCredential.id and WebAuthnCredential.publicKey respectively.

verifyRegistrationResponse() has been updated accordingly to return a new credential value of type WebAuthnCredential. Update code that stores credentialID, credentialPublicKey, and counter out of verifyRegistrationResponse() to store credential.id, credential.publicKey, and credential.counter instead:

Before:

const { registrationInfo } = await verifyRegistrationResponse({...});

storeInDatabase(
  registrationInfo.credentialID,
  registrationInfo.credentialPublicKey,
  registrationInfo.counter,
  body.response.transports,
);

After:

const { registrationInfo } = await verifyRegistrationResponse({...});

storeInDatabase(
  registrationInfo.credential.id,
  registrationInfo.credential.publicKey,
  registrationInfo.credential.counter,
  registrationInfo.credential.transports,
);

Update calls to verifyAuthenticationResponse() to match the new credential argument that replaces the authenticator argument:

Before:

import { AuthenticatorDevice } from '@simplewebauthn/types';

const authenticator: AuthenticatorDevice = {
  credentialID: ...,
  credentialPublicKey: ...,
  counter: 0,
  transports: [...],
};

const verification = await verifyAuthenticationResponse({
  // ...
  authenticator,
});

After:

import { WebAuthnCredential } from '@simplewebauthn/types';

const credential: WebAuthnCredential = {
  id: ...,
  publicKey: ...,
  counter: 0,
  transports: [...],
};

const verification = await verifyAuthenticationResponse({
  // ...
  credential,
});

v10.0.1

Packages

• @simplewebauthn/[email protected]

Changes

• [server] isoCrypto.verify() now has better support for signature verification with ECC public keys using P-256, P-385, and P-521 curves (#594, with thanks to @nlordell)

v10.0.0 - The one that goes up to 20

Thanks for everything, Node 16 and Node 18, but it's time to move on! The headlining change of this
release is the targeting of Node LTS v20+ as the minimum Node runtime. Additional developer-centric
quality-of-life changes have also been made in the name of streamlining use of SimpleWebAuthn on
both the back end and front end.

This release is packed with updates, so buckle up! Refactor advice for breaking changes is, as
always, offered below.

[server] generateRegistrationOptions() now expects Base64URLString for excluded credential IDs

The isoBase64URL helper can be used to massage Uint8Array credential IDs into base64url strings:

Before

const opts = await generateRegistrationOptions({
  // ...
  excludeCredentials: devices.map((dev) => ({
    id: dev.credentialID, // type: Uint8Array
    type: 'public-key',
    transports: dev.transports,
  })),
});

After

import { isoBase64URL } from '@simplewebauthn/server/helpers';

const opts = await generateRegistrationOptions({
  // ...
  excludeCredentials: devices.map((dev) => ({
    id: isoBase64URL.fromBuffer(dev.credentialID), // type: string
    transports: dev.transports,
  })),
});

The type argument is no longer needed either.

---

[server] generateAuthenticationOptions() now expects Base64URLString for allowed credential IDs

Similarly, the isoBase64URL helper can also be used during auth to massage Uint8Array credential
IDs into base64url strings:

Before

const opts = await generateAuthenticationOptions({
  // ...
  allowCredentials: devices.map((dev) => ({
    id: dev.credentialID, // type: Uint8Array
    type: 'public-key',
    transports: dev.transports,
  })),
});

After

import { isoBase64URL } from '@simplewebauthn/server/helpers';

const opts = await generateAuthenticationOptions({
  // ...
  allowCredentials: devices.map((dev) => ({
    id: isoBase64URL.fromBuffer(dev.credentialID), // type: Base64URLString (a.k.a string)
    transports: dev.transports,
  })),
});

The type argument is no longer needed either.

---

[server] credentialID returned from response verification methods is now a Base64URLString

It is no longer necessary to manually stringify credentialID out of response verification methods:

Before

import { isoBase64URL } from '@simplewebauthn/server/helpers';

// Registration
const { verified, registrationInfo } = await verifyRegistrationResponse({ ... });
if (verified && registrationInfo) {
  const { credentialID } = registrationInfo;
  await storeInDatabase({ credIDString: isoBase64URL.fromBuffer(credentialID), ... });
}

// Authentication
const { verified, authenticationInfo } = await verifyAuthenticationResponse({ ... });
if (verified && authenticationInfo) {
  const { newCounter, credentialID } = authenticationInfo;
  dbAuthenticator.counter = authenticationInfo.newCounter;
  await updateCounterInDatabase({
    credIDString: isoBase64URL.fromBuffer(credentialID),
    newCounter,
  });
}

After

// Registration
const { verified, registrationInfo } = await verifyRegistrationResponse({ ... });
if (verified && registrationInfo) {
  const { credentialID } = registrationInfo;
  await storeInDatabase({ credIDString: credentialID, ... });
}

// Authentication
const { verified, authenticationInfo } = await verifyAuthenticationResponse({ ... });
if (verified && authenticationInfo) {
  const { newCounter, credentialID } = authenticationInfo;
  dbAuthenticator.counter = authenticationInfo.newCounter;
  await updateCounterInDatabase({ credIDString: credentialID, newCounter });
}

---

[server] AuthenticatorDevice.credentialID is now a Base64URLString

Calls to verifyAuthenticationResponse() will need to be updated to encode the credential ID to a
base64url string:

Before

const verification = await verifyAuthenticationResponse({
  // ...
  authenticator: {
    // ...
    credentialID: credIDBytes,
  },
});

After

import { isoBase64URL } from '@simplewebauthn/server/helpers';

const verification = await verifyAuthenticationResponse({
  // ...
  authenticator: {
    // ...
    credentialID: isoBase64URL.fromBuffer(credIDBytes),
  },
});

---

[server] isoBase64URL.isBase64url() is now called isoBase64URL.isBase64URL()

Note the capitalization change from "url" to "URL" in the method name. Update calls to this method
accordingly.

---

[server] generateRegistrationOptions() will now generate random user IDs

[browser] user.id is now treated like a base64url string in startRegistration()

[browser] userHandle is now treated like a base64url string in startAuthentication()

A random identifier will now be generated when a value is not provided for the now-optional userID
argument when calling generateRegistrationOptions(). This identifier will be base64url-encoded
string of 32 random bytes. RPs that wish to take advantage of this can simply omit this
argument.

Additionally, startRegistration() will base64url-decode user.id before calling WebAuthn. During
auth startAuthentication() will base64url-encode userHandle in the returned credential. This
should be a transparent change for RP's that simply feed @simplewebauthn/server options output
into the corresponding @simplewebauthn/browser methods.

However, RP's that wish to continue generating their own user identifiers will need to take
additional steps to ensure they get back user IDs in the expected format after authentication.

Before (SimpleWebAuthn v9)

// @simplewebauthn/server v9.x
const opts = generateRegistrationOptions({
  // ...
  userID: 'randomUserID',
});

// @simplewebauthn/browser v9.x
const credential = await startAuthentication(...);
sendToServer(credential);

// @simplewebauthn/server v9.x
const credential = await receiveFromBrowser();
console.log(
  credential.response.userhandle, // 'randomUserID'
);

After (SimpleWebAuthn v10)

// @simplewebauthn/server v10.x
import { isoUint8Array } from '@simplewebauthn/server/helpers';

const opts = generateRegistrationOptions({
  // ...
  userID: isoUint8Array.fromUTF8String('randomUserID'),
});

// @simplewebauthn/browser v10.x
const credential = await startAuthentication(...);
sendToServer(credential);

// @simplewebauthn/server v10.x
import { isoBase64URL } from '@simplewebauthn/server/helpers';

const credential = await receiveFromBrowser();
console.log(
  isoBase64URL.toUTF8String(credential.response.userhandle), // 'randomUserID'
);

---

[server] isoBase64URL.toString() and isoBase64URL.fromString() have been renamed

The method names have been updated to reflect the use of UTF-8 string encoding:

Before:

const foo = isoBase64URL.toString('...');
const bar = isoBase64URL.fromString('...');

After:

const foo = isoBase64URL.toUTF8String('...');
const bar = isoBase64URL.fromUTF8String('...');

---

[server] rpID is now a required argument when calling generateAuthenticationOptions()

Update calls to this method to specify the same rpID as passed into
generateRegistrationOptions():

Before

  generateRegistrationOptions({ rpID: 'example.com', ... });
generateAuthenticationOptions();

After

  generateRegistrationOptions({ rpID: 'example.com', ... });
generateAuthenticationOptions({ rpID: 'example.com' });
