Verify the human.
Stop impersonation.

LastID adds cryptographic proof of human identity and authority to existing authentication systems.

The Problem

Authentication proves access.

It does not prove who the human is.

MFA tokens can be phished, replayed, or socially engineered

Caller ID is trivially spoofed with off-the-shelf tools

Email headers are unsigned and easily forged

Vendors and contractors are outside your authentication perimeter

AI-generated voice and video remove the last human signals

Impersonation is now the dominant failure mode in enterprise security.

The Solution

Cryptographic proof of human identity.

Issued once. Verified anywhere. Controlled by the user.

Identity rooted to hardware

Private keys generated in Secure Enclave, StrongBox, or TPM. Never extracted.

Pairwise identifiers

Each verifier receives a unique DID. No cross-organization tracking.

Verifiable credentials

KYC-verified personas, employment, authority. Selective disclosure via SD-JWT.

Anonymous age proofs

Prove over-18 or over-21 without revealing date of birth.

OAuth / OIDC integration

Drop-in identity provider. Works with existing auth infrastructure.

Cross-organization trust

Verify any party on the network. No directory federation or B2B integration.

SDK verification

Verify credentials offline. No round-trip to issuer required.

Who This Is For

Security Leaders

"How do we stop impersonation before the next board meeting?"

"How do we verify vendors without federating directories?"

"How do we verify humans in AI-assisted workflows?"

Identity Architects

"How does this integrate with our existing OIDC stack?"

"Can we verify external parties without B2B federation?"

"What's the credential format and verification flow?"

Security Engineers

"How do we verify credentials offline at the edge?"

"What's the SDK integration complexity?"

"How do we gate high-risk operations on human identity?"

If you're evaluating impersonation controls, this is for you.

Use Cases

Where Identity Verification Matters

Messaging

Gated Communications

Verify sender identity before connecting. Text messaging now, voice and video coming soon.

Finance

High-Value Transactions

Confirm human identity for wire transfers, account changes, and sensitive operations. Not just authentication—verification.

Third Party

Vendor Verification

Verify external parties on the network without directory federation. They prove their credential, you verify cryptographically.

Enterprise

Access Delegation

Issue verifiable credentials for authority and capability. Prove employment, role, or permission without exposing PII.

Compliance

Age-Restricted Services

Cryptographic proof of age without revealing date of birth. Anonymous, verifiable, compliant.

Support

Account Recovery

Recover access through verified human identity, not security questions. Eliminates social engineering attacks on support.
