Release notes:

🔑 WebAuthn passkeys

New Credentials virtual authenticator, available via BrowserContext.Credentials, lets tests register passkeys and answer navigator.credentials.create() / navigator.credentials.get() ceremonies in the page — no real hardware key required, works in all browsers:

var context = await browser.NewContextAsync();

// Seed a passkey your backend provisioned for a test user.
await context.Credentials.CreateAsync("example.com", new()
{
Id = credentialId,
UserHandle = userHandle,
PrivateKey = privateKey,
PublicKey = publicKey,
});
await context.Credentials.InstallAsync();

var page = await context.NewPageAsync();
await page.GotoAsync("https://example.com/login");
// The page's navigator.credentials.get() is answered with the seeded passkey.

You can also let the app register a passkey once in a setup test, read it back with Credentials.GetAsync(), and seed it into later tests — see Credentials for details.

🗃️ Web Storage

New WebStorage API, available via Page.LocalStorage and Page.SessionStorage, reads and writes the page's storage for the current origin:

await page.LocalStorage.SetItemAsync("token", "abc");
var token = await page.LocalStorage.GetItemAsync("token");
var items = await page.SessionStorage.ItemsAsync();

New APIs

• APIResponse.SecurityDetailsAsync() and APIResponse.ServerAddrAsync() mirror the browser-side Response.SecurityDetailsAsync() and Response.ServerAddrAsync().
• New option ArtifactsDir in BrowserType.ConnectOverCDPAsync() controls where artifacts such as traces and downloads are stored when attached to an existing browser.
• New option Cursor in Screencast.ShowActionsAsync() controls the cursor decoration rendered for pointer actions.
• The OnFrame callback in Screencast.StartAsync() now receives a Timestamp of when the frame was presented by the browser.

🛠️ Other improvements

• Playwright now supports Ubuntu 26.04.
• HAR and trace recordings now include WebSocket requests.
