Keytos

Overview

Keytos provides passwordless authentication and certificate management with a strong focus on Microsoft Azure and Entra environments. Founded in 2020 in Seattle, it appeals to Microsoft-centric teams that want to combine phishing-resistant sign-in with automated PKI, consolidating certificate lifecycle and authentication that would otherwise need several tools.

What it is good at

Tight Azure and Entra integration is the strength. Keytos automates certificate issuance and rotation, supports FIDO2 and passkey authentication, and slots into Microsoft-native workflows so that PKI and phishing-resistant auth become one managed motion. For teams already standardized on Entra ID, that removes a lot of the manual certificate toil that usually surrounds passwordless rollouts. It also reaches adjacent credential types such as SSH and code-signing certificates, so the same automation that protects user sign-in extends to the machine and developer credentials that frequently go unmanaged and become an audit problem later.

Where it falls short

Its value drops sharply outside the Microsoft ecosystem, and breadth is narrower than general-purpose MFA vendors. It is not a multi-cloud identity suite, and it expects Entra as the backbone. Multi-cloud or non-Microsoft shops will find the fit awkward.

Pricing

Subscription with published pricing. Model certificate and seat volume with the TCO calculator.

Best for, and who should look elsewhere

Choose it for Azure and Entra shops that want passwordless plus certificate automation in one place. Teams outside Microsoft should look at Yubico for hardware keys or Duo for managed MFA; those wanting broad credential orchestration should compare Axiad. See the full MFA directory.

Bottom line

A practical passwordless-and-PKI choice for Microsoft-centric organizations, and a poor fit for everyone else.
