The industry is steadily moving toward a passwordless future, and real-world deployment data shows that passkeys are gaining traction across top global platforms. With support from major players like Google, Apple, Microsoft, Amazon and LinkedIn, passkeys are emerging as a secure, user-friendly alternative to traditional passwords and SMS OTPs.

Global Adoption Insights

• Out of the top 50 global websites by traffic, 19 already support passkeys either as a primary login method or as part of MFA.
• Leaders include Google, YouTube, Facebook, Instagram, TikTok, Amazon, Microsoft, LinkedIn, Apple, and Yahoo Japan.
• Adoption remains uneven, with many high-traffic sites still relying on legacy authentication.

Case Study Highlights

• Yahoo Japan - 11% adoption across 55M users, with 2.29–15.35% higher registration rates, 2.6x faster logins, and 25% fewer support requests.
• Mercari - Achieved an 82.5% login success rate with passkeys vs 67.7% for SMS OTP, and cut login times from 17s to 4.4s.
• Kayak - Reduced login and registration times by 50%, alongside fewer authentication-related support tickets.
• Dashlane - Reached an impressive 92% passkey conversion rate, a 70% improvement over passwords.

Business & Compliance Benefits

• Security - Resilient against phishing, credential stuffing, and password reuse.
• User Experience - Faster, smoother logins reduce friction and support costs.
• Compliance - Supports mandates from PSD2, GDPR, and NIST by strengthening authentication while minimizing user disruption.

Implementation Challenges & UX Considerations

• Device and browser support - Inconsistent onboarding flows across OS/browser ecosystems.
• Fallback authentication - Needed for unsynced or lost passkeys but can introduce security risks.
• Multiple passkeys support - Essential as cookies, profiles, or device resets may wipe passkeys.

Strategic Takeaway

Passkeys deliver security, compliance, and superior UX at scale, but successful rollout depends on thoughtful design, particularly around fallback flows and multi-device support. For businesses, adopting passkeys is not just about strengthening defenses but also boosting conversion, retention, and customer trust.
