## Overview

1Kosmos combines passwordless authentication with identity verification on its BlockID platform, using a privacy-focused, distributed architecture to bind a verified, proofed identity to every login. Founded in 2018, it targets enterprise and government buyers who care not just about a strong second factor but about knowing who is actually behind the credential. That pairing of verification and authentication is its defining angle.

## What it is good at

The differentiator is high-assurance enrollment. By verifying documents and biometrics at the point of registration and then issuing a [passkey-style](https://startwithidentity.com/standards/webauthn-fido2/), device-bound credential, it raises assurance far above a typical [MFA](https://startwithidentity.com/glossary/mfa/) deployment. The credentials are [phishing-resistant](https://startwithidentity.com/glossary/phishing-resistant-mfa/), and the same platform can serve both workforce and customer journeys, which is useful where identity proofing and login need to be one motion rather than two products.

## Where it falls short

The decentralized, identity-bound model is distinctive but adds conceptual overhead, and buyers should expect a longer evaluation than a simple authenticator. It is an authentication-and-verification specialist, not a full IAM suite, so [SSO](https://startwithidentity.com/vendors/mfa/), provisioning, and governance still come from your existing platform. References at very large scale are fewer than the category giants.

## Pricing

Subscription, quote-based. Scope it against your real user counts and verification volume with the [TCO calculator](https://startwithidentity.com/tools/tco-calculator/).

## Best for, and who should look elsewhere

Choose it when verified identity and passwordless must arrive together, especially in regulated or government settings that need proofed enrollment. Teams that only need a second factor should look at [Duo](https://startwithidentity.com/vendors/mfa/duo/) or [Microsoft Authenticator](https://startwithidentity.com/vendors/mfa/microsoft-authenticator/); teams wanting standards-pure FIDO at scale should consider [Nok Nok Labs](https://startwithidentity.com/vendors/mfa/nok-nok-labs/). See the full [MFA directory](https://startwithidentity.com/vendors/mfa/).

## Bottom line

A strong fit when you need proofed, high-assurance identity and passwordless in one platform, not just another second factor.
