👋Goodbye Password Managers. Hello Multifactor.
Password managers are broken. We changed the game with secure one-click sharing, instant revocation, and powerful agentic integrations.
Password Managers
Multi — The First Provably Secure AI Assistant
Multi is the only AI agent that can securely access your own accounts when asked, just by storing them in Multifactor. Strong access controls ensure you remain in control throughout the process.
Natural Language Commands
Chat with Multi just like your favorite AI assistant. Watch as it securely uses your own accounts to automate tasks and provide personalized answers.
Cross-Account Access
Multi can securely log in to any online account you have stored in Multifactor. No additional configuration needed.
Secure Account Use
Multi loads your accounts in a secure, isolated cloud browser. Raw credentials are never visible to the AI or transmitted to third parties.
Strongly Enforced Permissions
Multi can only access the specific account features you allow. You'll know as soon as it tries to do something new, so you can approve or deny the request.
Powerful Automations
Create reusable playbooks that combine natural language commands and pre-configured permissions to automate complex tasks with a single click.
The World's Best Account Manager
Multifactor redefines zero-trust account management with fine-grained sharing, detailed audit trails, and a world-class security architecture.
Unified Secure Platform
Multifactor puts all of your online accounts at your fingertips in one secure, easy-to-use vault, available on any device you need it.
Instant Access Control
Because actual passwords are never shared, access changes take instant effect—no password resets required.
Multi-Factor Management
What's in a name? Multifactor lets you manage passwords, passkeys, 2FA codes, and more in one secure, unified vault.
Fine-Grained Permissions
Don't just share full access—share specific permissions, like “read transactions” but not “make transfers.”
Detailed Event History
See not only who accessed which accounts, but also what they did with them, paired with a digital signature that provides non-repudiable cryptographic proof.
Zero Trust Cryptography
Our zero-trust architecture uses advanced post-quantum encryption techniques to ensure that nobody else (not even us) can access your credentials without posessing all of your root authentication factors.
A Foundation of Innovative Research
Multifactor is built on a decade of user-centric identity security research, focusing on cryptographic solutions that enhance security without compromising user experience. Our award-winning work, published in top academic venues like USENIX Security, PETS, IEEE EuroS&P, ACM UIST, and ACM CHI, is preferred over legacy identity solutions by end users and security practitioners alike.
Frequently Asked Questions
Built by Security Experts
We're on a mission to re-define “zero trust” for the modern, agentic era. That's why we're a registered Public Benefit Corporation, publish our application source code, and use a best-in-class post-quantum security architecture based on CRYSTALS Kyber and CRYSTALS Dilithium.
