The Great Authentication Divide: How Passkeys Are Reshaping Digital Identity in Emerging Markets

Guwahati, India — When 28-year-old café owner Ritu Sharma tried to access her business bank account from her sister's Android phone last month, she encountered a problem that didn't exist in the password era. Despite having her biometric authentication set up, the banking app refused to recognize her on the unfamiliar device. "I was locked out of my own account during peak business hours," Sharma recalls. "The bank said I needed to 'transfer my passkey'—whatever that means."

Sharma's experience highlights a growing paradox in digital authentication: while passkeys represent the most significant security advancement since two-factor authentication, their real-world implementation is creating new fractures in the digital experience—particularly in markets where users frequently share devices or switch between ecosystems. As global tech giants push toward a passwordless future, the transition is exposing deep disparities in how different regions experience digital identity management.

The Authentication Revolution's Unseen Costs

From Universal Access to Ecosystem Silos

The password system, for all its flaws, had one undeniable advantage: universality. A string of characters could be entered on any device, anywhere in the world. Passkeys, by design, abandon this universality in favor of security. Each passkey is a cryptographic key pair—one public, one private—where the private key never leaves the user's device. This makes phishing virtually impossible (Google's 2025 Security Report found passkey-protected accounts experienced 99.6% fewer successful phishing attempts) but creates a fundamental shift in how we think about digital access.

The ecosystem lock-in effect is particularly pronounced in regions with heterogeneous device landscapes. In Indonesia, where 65% of users own devices from at least two different manufacturers, passkey implementation has led to a 30% increase in customer service calls to banks and government services, according to data from Jakarta's Digital Transformation Agency. "We're seeing a new digital divide," notes Dr. Ananya Bhattacharya, a cybersecurity researcher at IIT Guwahati. "It's not just about having internet access anymore—it's about which ecosystem you're locked into and how many devices you can afford to authenticate."

The Shared Device Dilemma

In many emerging markets, device sharing isn't just common—it's an economic necessity. A 2024 study by GSMA found that in Bangladesh, Pakistan, and Nigeria, more than 60% of smartphone users share their primary device with at least one other person. Passkeys, which are tied to individual devices and user profiles, create friction in these scenarios.

The Regional Implementation Gap

The Economic Impact: When Security Creates Exclusion

Small Businesses Bear the Brunt

For micro-enterprises that rely on shared devices, passkey requirements are creating operational bottlenecks. In Vietnam, where street vendors increasingly use digital payment systems, 32% reported losing sales when they couldn't access their accounts on borrowed devices during the 2025 Tet holiday season. "I had to turn away customers because my phone died and my cousin's phone wouldn't recognize my fingerprint for the payment app," recounts Hanoi street food vendor Le Thi Mai.

The Gig Economy's Authentication Crisis

Passkey implementation has had particularly severe consequences for gig workers who rely on shared or rented devices. In Indonesia, where 4.2 million people work in the ride-hailing and delivery sectors:

• 1 in 5 drivers report being locked out of work for >24 hours due to device changes
• Emergence of "account rental" markets where workers lease authenticated devices
• Gojek and Grab have both introduced "temporary passkey" systems for shared devices, adding operational complexity

Technical Workarounds and Their Consequences

The Rise of Passkey Brokers

In response to these challenges, informal solutions are emerging across the region:

• Passkey Transfer Services: Shops in Delhi's Nehru Place and Bangkok's Pantip Plaza now offer passkey migration between devices for 300-500 baht (~$15)
• Family Authentication Plans: Some banks in the Philippines allow a primary account holder to authorize secondary devices for family members
• Biometric Workarounds: In Vietnam, some users register multiple fingerprints on a single device to enable shared access

"These solutions defeat the security purpose of passkeys," warns cybersecurity expert Arjun Mehta. "We're seeing the creation of new attack vectors as users store passkey backups in unencrypted cloud services or share biometric data."

Corporate Responses: Hybrid Systems Emerge

Recognizing these challenges, some organizations are implementing hybrid approaches:

• HDFC Bank (India): Offers "guest mode" passkeys that expire after 24 hours for shared device scenarios
• Grab (Southeast Asia): Maintains parallel password and passkey systems, adding 18% to authentication costs
• Bangkok Metropolitan Administration: Created "community authentication kiosks" in low-income neighborhoods

The Path Forward: Balancing Security and Inclusion

Technical Solutions in Development

The industry is beginning to address these challenges through:

• Cross-Device Passkey Protocols: Google and Apple are testing "temporary passkey delegation" standards expected in 2026
• Biometric Family Profiles: Samsung's 2025 flagship devices will support up to 5 biometric profiles per passkey
• Hardware Tokens: Yubico and others are developing $5 passkey tokens for shared device scenarios

Policy Considerations

Regulators are grappling with how to:

• Mandate interoperability standards without stifling innovation
• Balance security requirements with digital inclusion goals
• Regulate emerging passkey broker markets

"The passkey transition isn't just a technical challenge—it's a socio-economic one," emphasizes Dr. Bhattacharya. "We need authentication systems that work for a family sharing one phone in Assam as well as they work for a tech professional with three devices in Silicon Valley."

Conclusion: The Authentication Paradox

Passkeys undeniably represent the future of digital security. Their ability to eliminate phishing and credential stuffing attacks makes them a necessary evolution from password-based systems. However, their implementation has exposed a fundamental tension in digital identity management: the conflict between absolute security and practical accessibility.

In emerging markets where device sharing is common and multi-ecosystem usage is the norm, passkeys are creating new forms of digital exclusion. The technology's success will ultimately depend not just on its security benefits, but on how well it can adapt to the complex realities of how people actually use technology in different cultural and economic contexts.

As Ritu Sharma discovered when she couldn't access her business account, the passwordless future isn't just about eliminating something old—it's about navigating the unintended consequences of something new. The challenge for technologists and policymakers alike will be ensuring that in our rush to build more secure systems, we don't accidentally build more exclusive ones.
