Importing and exporting passkeys and passwords is now available on Android. This resolves the security risks of legacy plaintext CSV exports and the inability to migrate passkeys across providers through secure, OS-level peer-to-peer data transfer.

By setting up `https://<your-domain>/.well-known/change-password` to redirect (302/303/307) to your actual password update page, Chrome, Safari, and major password managers can guide users directly to your change password form.

Notifications for PWAs on macOS are getting a major upgrade starting in Chrome 152! Notifications will now be natively attributed to the PWA itself—displaying the app's own name and custom icon instead of "Google Chrome"—and will integrate seamlessly with macOS System Settings and Focus modes.

The Email Verification Protocol has some updates! The Email Verification origin trial (introduced in Chrome 150) offers a progressive enhancement that verifies email ownership directly with the email provider through the browser—eliminating the need to send an outbound email altogether.

This includes the passkey skills, so your agent implements passkeys the right way from the start. For example, it can visually display which password manager each passkey is stored in in the passkey management page, making credential management clear for users.

Personally, the most exciting auth-related feature since passkeys: Chrome just announced an origin trial for the Email Verification Protocol (EVP).

Sign-in success jumped from ~70% to >99%, already in production across 50+ regional domains. Passkey adoption often faces two pain points: users abandoning at creation prompts, and sign-in failures from device-server credential drift.

氷河期展滑り込んできた。ネアンデルタール人とクロマニヨン人の違いが知れて良かった。実は今も氷河期の最中で、間氷期という比較的温暖な時期なだけだというのは目からウロコだった。地球は奥深い。

There are best practices for how to promote #passkeys on your app. This blog post goes through different surfaces to remind your users about passkey benefits, their approaches and case studies. The same practices apply to the web as well. android-developers.googleblog.com/2025/09/best...

WebAuthn "immediate mediation" lets you build a dynamic #passkey sign-in experience upon checkout for example , falling back to a regular form based sign-in when no passkeys are available. Try it as an origin trial today. developer.chrome.com/blog/webauth...

OK, it's done. In two hours, I could create an RSS reader with AI summarization feature + passkey based sign-up and sign-in. I didn't read or write a single line of code. This is so cool...
