Use Cases

Explore how ByteAuth's passwordless authentication could be applied across different industries and scenarios.

Travel & Aviation

Self-Service Kiosks

Imagine a traveler approaching a self-service kiosk. Instead of typing confirmation codes or credentials on a shared screen, they scan a QR code with their phone. Biometric confirmation provides secure authentication without exposing sensitive data to the public terminal.

Potential Benefits

  • Reduced credential exposure on public terminals
  • No typing passwords where others can observe
  • Biometric verification adds identity assurance
  • Cryptographic signatures provide audit trails

Possible Applications

  • Check-in and boarding systems
  • Loyalty program authentication
  • Lounge access verification
  • Self-service rebooking terminals

Integration Approach

ByteAuth provides REST APIs and SDKs (Laravel, Next.js) that can be integrated into web-based kiosk applications. Custom integrations with existing systems would require development work specific to each platform.

Guest Services & Access

A guest arrives and approaches a self-service station. Rather than providing identification documents to a stranger or typing credentials on a shared device, they authenticate via their personal phone with biometric confirmation, maintaining privacy and security.

Potential Benefits

  • Enhanced guest privacy during check-in
  • No credential storage on shared terminals
  • Reduced friction for returning guests
  • Verifiable identity for access control

Possible Applications

  • Self-service check-in/check-out
  • Room access authorization
  • Amenity and service access
  • Loyalty program verification

Integration Approach

ByteAuth can be integrated into web-based property management interfaces. Integration with specific PMS platforms, access control systems, or mobile key solutions would require custom development.

High-Value Asset Access

A customer arrives for a scheduled appointment involving access to high-value assets. Instead of presenting multiple forms of identification, they authenticate via ByteAuth, providing cryptographically verifiable proof of identity before gaining access.

Potential Benefits

  • Strong identity verification for high-value transactions
  • Cryptographic audit trail for compliance
  • Reduced identity fraud risk
  • Streamlined customer experience

Possible Applications

  • Test drive authorization
  • Equipment rental verification
  • High-value product access
  • Appointment check-in systems

Integration Approach

ByteAuth provides web-based authentication that can be integrated into customer-facing applications. Integration with inventory systems, key management, or CRM platforms would require custom development work.

How ByteAuth Works

The same cryptographic principles that secure Bitcoin, applied to authentication.

QR Code Challenge

Your application displays a QR code containing a cryptographic challenge. This challenge is unique and time-limited.

Biometric Confirmation

The user scans with ByteVault and confirms their identity using their device's biometric security (Face ID, Touch ID, etc.).

Cryptographic Signature

The app signs the challenge using ECDSA with the secp256k1 curve — the same cryptography used in Bitcoin.

Server Verification

Your server verifies the signature against the user's registered public key. No passwords are transmitted or stored.

Important Information

Illustrative Examples: The use cases presented on this page are illustrative examples of potential applications for ByteAuth technology. They represent possible scenarios where passwordless authentication could provide value, not confirmed implementations or partnerships.

Integration Requirements: Implementing ByteAuth in any specific environment requires development work. While we provide SDKs for Laravel and Next.js, integration with third-party systems, proprietary platforms, or specialized industry software would require custom development specific to those systems.

No Endorsements: References to industries, business types, or scenarios do not imply endorsements, partnerships, or certifications from any third-party organizations, standards bodies, or companies in those industries.

Security Considerations: While ByteAuth uses cryptographic methods (ECDSA/secp256k1) that have been extensively tested in other applications including Bitcoin, the security of any implementation depends on proper integration, configuration, and operational practices. Organizations should conduct their own security assessments.

Compliance: Organizations are responsible for ensuring their use of ByteAuth complies with applicable laws, regulations, and industry requirements in their jurisdiction and sector.
