Multifactor

Multifactor operates a credential and account management platform positioned as an alternative to conventional password managers. The product stores passwords, passkeys, two-factor authentication codes and other authentication factors in a single vault available across devices, and lets users share access to online accounts by sending a link rather than by disclosing the underlying passwords. Because raw credentials are not transferred, access can be granted or revoked immediately without password resets, and sharing can be scoped to specific permissions (for example, viewing transactions but not initiating transfers). The platform records detailed event history covering both who accessed an account and what actions were taken, accompanied by digital signatures intended to provide non-repudiable cryptographic proof.

The company also offers Multi, an AI assistant in early access that can log into accounts stored in Multifactor on the user's behalf. Multi runs sessions in an isolated cloud browser so that raw credentials are not exposed to the model or sent to third parties, operates only within permissions the user has granted, prompts for approval when it attempts a new action, and supports reusable "playbooks" that combine natural-language instructions with pre-configured permissions to automate multi-step tasks.

Multifactor describes its architecture as zero trust, using post-quantum encryption so that credentials cannot be accessed without all of the user's root authentication factors, including by the company itself.

Founding story

The company states it is built on roughly a decade of user-centric identity security research focused on cryptographic approaches intended to improve security without degrading usability.

Business model

Freemium software platform: a free consumer tier with paid, custom-priced enterprise plans for organizations.

Baseline features are free and unlimited for individuals and small groups, while enterprise plans are custom priced and add advanced auditing and compliance, priority support with SLAs, and cloud RBAC and SSO integrations.

Traction

The company reports research underpinning the product has been published in academic venues including USENIX Security, PETS, IEEE EuroS&P, ACM UIST and ACM CHI, and describes the work as award-winning and preferred by end users and security practitioners over legacy identity solutions.

Latest developments

Multifactor announced the acquisition of Keypo, stating the deal is intended to accelerate zero-trust security for AI agents, and opened general sign-ups alongside early access to its Multi AI assistant.
