From Passwords to Passcards to Passkeys: How Identity Is Evolving for Access

Introduction: The Death of the Password

It started with something simple: a password. Then came PINs, access cards, smartcards, biometric scanners, mobile tokens, and now, passkeys. Identity verification has evolved from something you know, to something you carry, and finally to something you are.

In physical spaces, this evolution has been just as dramatic. Gone are the days of laminated badges dangling from lanyards. Today’s enterprises demand seamless, touchless, secure, and intelligent access systems.

At the heart of this transformation is Physical Identity and Access Management (PIAM)—the invisible engine powering the secure movement of people across physical spaces. And driving this engine into the future is Soloinsight’s CloudGate PIAM platform, engineered to integrate with the newest frontier of digital identity: passkeys.

This blog traces the journey from passwords to passcards to passkeys and explores how this shift is radically reshaping access control in Fortune 500 environments, global campuses, and decentralized workforces.

The First Era: Passwords and Physical Security

Passwords were never meant to secure physical space, but they inadvertently became part of the first wave of digital identity.

Access terminals. Secure computers. VPNs.Users typed in static strings of text—often weak, reused, or written on sticky notes.

In the physical world, this meant:

• Lobby terminals for employee check-ins

• Badge printers linked to HR systems

• Manual logbooks for guests and contractors

These methods were insecure, slow, and highly dependent on human intervention. Breaches weren’t just digital—they were physical.

The Badge Era: Enter the Passcard

The invention of magnetic stripes and RFID transformed access control. Companies could now issue employee ID cards that opened doors automatically.

This gave rise to:

• Badge readers and turnstiles

• Role-based access controls tied to job titles

• Attendance tracking systems for HR and compliance

But with this convenience came risks:

• Cloning and spoofing of badges

• Lost or stolen cards granting unauthorized access

• High administrative overhead for provisioning and revocation

• Inability to adapt to dynamic roles in real time

Enterprises realized: The badge had become the bottleneck.

Mobile Access: The Wallet Revolution

With smartphones becoming ubiquitous, the next natural step was integrating access into digital wallets.

Soloinsight’s CloudGate PIAM platform was among the first to support:

• Employee badge in Apple Wallet

• Corporate badge in Google Wallet

• NFC-based and QR-code based mobile credentials

• Role-based expiration and dynamic re-issuance of credentials

• Zero-touch access for hybrid workers and visitors

This wave offered more control and flexibility:

• Credentials could be pushed remotely

• Lost phones didn’t require a new badge—just credential revocation

• Visitors could be pre-enrolled and skip front-desk check-ins

• Multi-credential wallets allowed contractors to carry multiple org identities

Still, mobile wallets rely on hardware. And while they’re secure, they still depend on carrying something external.

Welcome to the Passkey Era

Passkeys are cryptographic credentials that replace passwords altogether. They don’t rely on secrets stored in a database, and they can’t be phished or guessed.

Instead of “typing” identity, passkeys prove identity using:

• Device-based cryptographic key pairs

• Biometric confirmation (Face ID, Touch ID)

• No shared secret transmission

In the context of PIAM, passkeys eliminate the need for badges, cards, even apps. You simply:

• Present your passkey from a trusted device

• Prove presence with a biometric or PIN

• CloudGate validates access through a decentralized verification handshake

The result? Frictionless, secure, portable access.

Physical Access with Passkeys: How It Works

1. User Enrollment

   An employee or contractor receives an invitation to enroll their device. CloudGate generates a cryptographic key pair unique to the user and device.

   
   

2. Credential Storage

   The private key stays secure on the user’s device. The public key is registered with CloudGate’s identity engine.

   
   

3. Access Attempt

   At a turnstile or door, the user’s device presents a passkey via Bluetooth, NFC, or QR.

   
   

4. Authentication

   The device signs a challenge. The user proves presence via fingerprint or face scan. CloudGate verifies the signature.

   
   

5. Policy Enforcement

   If the access is valid based on role, location, and time, entry is granted—no passwords, no badges, no fuss.

Use Cases: Evolving Access at Scale

🔒 Secure Data Centers

Engineers present passkeys from dedicated work phones. No badges needed. Entry is tied to just-in-time roles. Logging is instantaneous and encrypted.

🏢 Hybrid Corporate Campuses

Employees check into the office with their smartphones. No printed badges. Visitors receive temporary passkeys valid for the duration of their meeting.

🧪 Pharma & R&D Labs

Passkeys control access to cold storage units, cleanrooms, and restricted biohazard labs. Credentials expire automatically based on project assignments.

🛫 Airports and Border Control

Staff and contractors use passkeys linked to biometric profiles, allowing secure access to tarmac zones, control towers, and customs areas—with no physical document required.

Advantages of Passkeys + CloudGate

Benefit	Traditional Credentials	CloudGate + Passkeys
Credential Form	Badge/Card	Device-native cryptographic key
Authentication	Manual, PIN, signature	Biometric or local PIN
Risk	Lost/stolen cards	Device-bound, revocable
Revocation	Manual deactivation	Instant credential invalidation
Onboarding	Hours or days	Minutes
Audit Trail	Partial	Real-time and tamper-evident

Why Enterprises Are Moving Fast

Adopting passkeys for PIAM offers a strategic advantage:

• Reduced Help Desk Costs: Fewer badge replacements, fewer forgotten PINs

• Faster Onboarding: Provision credentials remotely, without physical meetings

• Zero Trust Alignment: Every access event is cryptographically validated

• Cross-Site Consistency: Same experience across buildings, cities, countries

• Resilience: No reliance on fragile physical cards or networks

Soloinsight’s CloudGate offers an out-of-the-box passkey integration framework that supports WebAuthn, FIDO2, and W3C standards—futureproofing your enterprise against evolving identity threats.

From Passive Access to Predictive Access

Passkeys don’t just open doors—they’re the key to smarter environments:

• Geo-fencing: Trigger access zones based on real-time location

• Contextual Authentication: Block access when anomalies are detected (e.g., after hours, unexpected locations)

• Behavioral AI: Learn access patterns and detect insider threats before they happen

With CloudGate, PIAM becomes predictive, preventive, and adaptive.

The Future: Beyond the Door

Soon, passkeys will integrate with:

• Digital Twin Environments: Simulating access behavior and identifying bottlenecks

• IoT Networks: Allowing workers to access not just rooms, but devices, sensors, and equipment

• Decentralized Identity Wallets: Merging physical and digital credentials for seamless interoperability

• Smart Cities: Where one passkey grants you access to workspaces, transit, hotels, and healthcare

This is not hypothetical. With CloudGate PIAM, it’s being piloted in Fortune 500 companies right now.

Conclusion: Unlocking the Future with a Single Touch

We’ve come a long way from passwords. From analog passes to smart badges to mobile wallets, each evolution was about reducing friction while increasing security.

Passkeys take us even further. They don’t just improve convenience—they eliminate entire categories of risk.

With CloudGate PIAM, Soloinsight is bringing this passkey revolution to the physical world—secure by design, scalable by architecture, and user-centric by default.

So when the next visitor walks into your building, they won’t need a badge. They’ll already have the key—in their pocket, on their phone, protected by a fingerprint.

The future of physical access isn’t something you carry. It’s something you are.
