Multifactor

Multifactor redefines how you manage and share digital identity, providing the best way to securely share online accounts with both human collaborators and powerful AI agents. Built on a robust Zero-Trust architecture, it offers trustless authentication, authorization, and auditing, eliminating the risk associated with traditional password sharing and complex factor management. This unified, cross-platform security platform is designed for anyone—from individuals and families seeking simplified management to organizations requiring advanced auditing and compliance.

Key Features

Multifactor goes beyond traditional credential vaults by managing the entire account ecosystem, ensuring maximum security and control for every interaction.

🔗 Secure, Instant Account Sharing

Share access to any stored online account with a simple, revocable link. Utilizing proprietary Checkpoint technology, Multifactor logs in on your behalf and securely shares a temporary session token, meaning raw passwords are never transmitted or revealed to the recipient. This enables immediate access control adjustments without ever requiring a password reset.

🤖 Integrated Multi AI Assistant

Securely automate complex tasks using the built-in AI agent. The Multi AI Assistant can securely log in to any stored account without additional configuration, executing tasks based on your natural language commands. Crucially, the AI loads accounts in a secure, isolated cloud browser, preventing credentials from being visible to the AI model itself and mitigating risks like prompt injection attacks.

🔒 Fine-Grained Permissions and Instant Revocation

Apply Zero-Trust principles to every shared account. You can define specific, fine-grained permissions—such as granting access to “read transactions” but explicitly denying the ability to “make transfers.” If access needs to be withdrawn, the instant revocation feature ensures the shared link and session token are immediately invalidated, securing the account instantly.

🔑 Unified Multi-Factor Management

Consolidate all your authentication factors—passwords, passkeys, 2FA codes, and recovery keys—into one secure, easy-to-use vault, accessible on any device. This unified approach simplifies complex security setups and ensures that all aspects of your identity are protected under a single, high-security architecture.

Use Cases

Multifactor provides tangible security and efficiency gains across multiple scenarios, ensuring you maintain control while enabling necessary access.

1. Secure Team Onboarding and Offboarding

When bringing a new contractor or team member onto a project, grant them access to only the necessary SaaS tools (e.g., analytics dashboards or specific social media accounts) using pre-configured, read-only permissions. When the contract ends, instantly revoke all access without the administrative burden of changing multiple passwords, ensuring zero lingering exposure.

2. Automating Cross-Platform Data Aggregation

Use the Multi AI Assistant to securely perform complex, cross-account tasks. For example, instruct the assistant via natural language to "Log in to my three bank accounts and two credit card portals and generate a report of all travel-related spending from the last quarter." The AI accesses the data securely within its isolated environment and presents the unified answer, saving hours of manual data fetching.

3. Managing Family Accounts Safely

Share access to essential family accounts (like utilities, streaming services, or online school portals) with a spouse or older child without ever exposing the master password or 2FA codes. Should a device be lost or a relationship change, access can be instantly cut off, protecting critical infrastructure without disrupting service for others.

Unique Advantages

Multifactor is built on a foundation of academic research and advanced cryptography, offering verifiable security advantages that differentiate it from traditional password managers.

Whole-Account Security, Not Just Passwords

Unlike conventional password managers that merely store credentials, Multifactor is a "whole account" manager. It stores and manages all factors—passwords, passkeys, 2FA codes, and recovery codes—enabling one-click login, secure sharing, and integration with AI agents, all managed under a single Zero-Trust policy.

Post-Quantum Secure Cryptography

To future-proof your data, Multifactor incorporates quantum-resistant CRYSTALS Kyber and CRYSTALS Dilithium encryption and signing algorithms. These layers are applied on top of standard encryption protocols (ECDH and ECDSA), creating a highly resilient cryptographic foundation resistant to potential attacks from future quantum supercomputers.

Zero Trust and Non-Repudiable Auditing

Multifactor’s Zero-Trust Architecture ensures that nobody—not even the company itself—can access your credentials without possession of all your root authentication factors. Furthermore, every access event is recorded in a detailed event history, paired with a non-repudiable digital signature, providing cryptographic proof of who accessed which account and what actions were taken.

Research-Backed and Trust-Driven

Multifactor is built on a decade of user-centric identity security research, with award-winning work published in leading academic venues. Our core principle is trust; selling personal user data is explicitly not, and will never be, part of our business model.

Conclusion

Multifactor provides the clarity, control, and cutting-edge security required to manage your digital life effectively in a world increasingly reliant on shared access and AI automation. By prioritizing Zero-Trust architecture and verifiable cryptography, we enable secure collaboration without sacrificing privacy or complexity.
