Problem

Multifactor addresses the security and control gap created when people and AI agents need to use existing online accounts. Passwords and legacy identity systems were not designed for agents acting on a user’s behalf, while conventional password managers make sharing broad, difficult to revoke, and hard to audit. The result is credential exposure, excessive permissions, and limited visibility into what an authorized collaborator actually did.

The highest-value use case is delegated access to sensitive, operationally important accounts without handing over the underlying credentials. Multifactor says early enterprise partners use AI agents across manufacturing supply chains worth more than $7.5 billion, where a security lapse can have serious consequences. More everyday examples include assistants accessing email and calendars, financial advisors managing client brokerage accounts, and teams or families sharing services without sharing passwords.

Product / Service

Multifactor is a zero-trust account-sharing platform centered on Checkpoint, which turns an online account into a shareable link. Users keep passwords, passkeys, two-factor codes, and other credentials in a unified vault, while recipients receive only the access they are authorized to use. Fine-grained permissions, instant revocation, and detailed event histories replace the coarse access and password resets associated with traditional sharing; the actual password is never shared.

For AI use, Multifactor’s Multi assistant operates accounts through an isolated cloud browser without exposing raw credentials to the AI or third parties. Users can approve or deny new permission requests, restrict the account functions an agent may use, and create reusable automations. The service is free for individuals and small groups, with custom enterprise plans offering advanced auditing, compliance, RBAC, SSO integrations, support, and SLAs. Its underlying architecture is moving toward trusted-execution and locally attested, cryptographic zero-trust controls.

Market

Multifactor competes in the emerging market for agentic identity and security: authentication, authorization, delegated account access, and auditing for AI agents. It also overlaps with password managers and enterprise identity or zero-trust platforms, but its stated ambition is to define a dedicated AI-security category rather than simply extend conventional IAM. Anon is a direct adjacent competitor, offering developers an SDK for automated authentication and permissioning in AI-driven applications; larger identity and security companies such as Okta, Cloudflare, and Wiz are better viewed as adjacent incumbents or category analogies than exact product matches.

The company is an active YC Fall 2025 startup and announced a $15 million seed round in December 2025 led by Nexus Venture Partners, with participation from Y Combinator and other funds and operators. Its public product is available on a free individual plan, while enterprise monetization is positioned around custom plans and advanced controls. Multifactor also acquired programmable-encryption company Keypo in June 2026 to accelerate Checkpoint. Public materials disclose early enterprise partners and funding, but not revenue, so the company is best described as early commercial with revenue status undisclosed rather than definitively pre-revenue.
