Google tests browser email verification to ease signups
Google is testing an Email Verification Protocol (EVP) in Chrome that allows the browser to verify a user controls an email address without sending a one-time password or magic link. Available via Chrome’s Origin Trial, EVP delivers cryptographic proof from the user’s email provider directly to websites, keeping verification inside the browser and falling back to traditional methods when a provider does not support the protocol. Google’s support could accelerate adoption given Chrome’s market share and Google’s position in email. Marketers could see higher sign-up conversion rates and improved first-party data quality. EVP is part of a broader shift toward browser-managed identity alongside passkeys and Federated Credential Management (FedCM).
A technical release from Google (a major platform) that could change how email verification and browser-managed identity work, affecting sign-up conversion flows and first-party data strategies for marketers.

Chrome modernizes web authentication with passkeys, EVP
At Google I/O 2026, the Chrome team published guidance and platform updates to modernize web authentication, emphasizing passkeys, federated sign-up, and browser-mediated verified attributes. Key technical features covered include the FedCM API for identity federation, the experimental Email Verification Protocol (EVP) for seamless verified email claims, the Digital Credentials API for selective disclosure from wallets, Immediate UI Mode (shipped in Chrome 149) and passkey autofill/conditional create for zero-friction enrollment, and Device Bound Session Credentials (DBSC) to tie sessions to hardware (experimental on Windows). The post describes patterns (e.g., "federate-then-upgrade"), cross-platform credential sharing (Digital Asset Links and Related Origin Requests), and recovery strategies, and cites case studies (pixiv, adidas) showing improved login success and passkey adoption.
Google allows verified political email to bypass spam filters
Google will launch a Gmail Verified Sender Program beginning September 8 that lets qualifying political organizations have their policy-compliant bulk email initially bypass Gmail’s standard spam filtering. Eligible participants (candidates, parties, PACs and other political entities registered with the Federal Election Commission or a state/local election authority) must verify identity and pass background checks via Campaign Verify, and only one email address per campaign domain may be verified. Participants must keep a spam complaint rate below 0.3% over any 14-day period or face policy violations. Although messages receive different initial handling, Gmail users retain controls to mark messages as spam, block senders, or unsubscribe. The change ties preferential inbox treatment to verified sender identity while keeping recipient feedback as a behavioral check.
Chrome 148 Adds Immediate UI Mode for Sign-In
Chrome 148 introduces Immediate UI mode, a new WebAuthn-related capability that streamlines sign-in by letting the browser proactively offer saved passkeys and managed passwords via an immediate login dialog. Sites can invoke an inline prompt (for example on a Sign In or Checkout button) to request credentials without redirecting to a separate login page or showing a form. If no credentials are available, the API rejects the request silently so sites can fall back to existing authentication methods. The feature replaces the origin-trial API behavior: developers should now set uiMode: 'immediate' in navigator.credentials.get(). The announcement was published on May 12, 2026 by Eiji Kitamura and José Luis Zapata on the Chrome Developers blog.
