Passwordless Authentication with Provisioning Keys

The server logs lit up with a single failed login attempt, then ten more, then hundreds. Static passwords were the weakest link, and the attackers knew it. Passwordless authentication with provisioning keys closes that gap. It removes passwords entirely and establishes trust through secure cryptographic operations at the moment of identity creation.

A passwordless authentication provisioning key is a one-time, high-entropy secret used to bootstrap a user or device into a system without sending reusable credentials over the network. The provisioning key can be issued for web apps, APIs, IoT devices, or internal tools. It acts as the root of trust for onboarding, generating asymmetric key pairs or token-based credentials in a controlled environment. Once used, it is destroyed, leaving no static secret to steal.

Implementing provisioning keys in passwordless workflows solves several problems at once:

• No stored passwords that can be leaked or cracked.
• No phishing surface for credential theft.
• Seamless initial enrollment for new devices or accounts.
• Auditable, scoped, and time-limited authentication events.

In a typical flow, an admin creates a provisioning key through an API or CLI. The client, upon receiving the provisioning key, uses it only once to request its permanent credentials—usually a public/private key pair stored securely in a hardware key store or OS-protected enclave. All future authentications are signed requests, verified against the stored public key. Revocation, rotation, and policy enforcement happen server-side.

Security depends on key generation and transport. Provisioning keys must be created with high entropy, constrained in scope, and expire quickly. Limit their distribution channels—send them via secure out-of-band methods like encrypted email or hardware token delivery. Log all issuance and usage events.

Passwordless authentication provisioning keys are not just a defensive measure; they accelerate onboarding and cut operational complexity. No password resets, no weak password policies, no endless credential rotation cycles. The identity is anchored in cryptographic trust from the start.
