Multifactor is a next-generation account-sharing and access-management platform built around zero-trust, post-quantum cryptography, and fine-grained permissioning. Rather than simply sharing credentials, users store their online accounts (passwords, passkeys, 2FA codes) in a secure vault and grant access to humans or AI agents by sending controlled links. Access can be revoked instantly, and the underlying credentials remain hidden. You can define precise permissions (for example, “read transactions” but not “initiate transfers”), capture detailed non-repudiable audit trails of every action, and enjoy built-in encryption and post-quantum security architecture that ensures only authorized parties ever gain access. ...
