framefilter

framefilter is an independent software publisher with a focused portfolio centered on hardware security key management and multi-factor authentication tooling. Its flagship product, keyroost, addresses the growing need for organizations and security-conscious individuals to configure and administer physical authentication devices. The software enables users to program Token2 Molto2 TOTP tokens, which are programmable hardware tokens used for time-based one-time password authentication, providing a hardware-backed alternative to smartphone authenticator apps. Beyond token programming, keyroost serves as a management utility for security keys implementing the major open authentication standards, including FIDO2 for passwordless and phishing-resistant web authentication, OATH for one-time password generation, OpenPGP for encryption and digital signing operations, and PIV (Personal Identity Verification) for smart card–based credential management. This breadth of protocol support places the product squarely within the identity and access management software category, where IT administrators, developers, and end users frequently need a single interface to initialize keys, configure credentials, and maintain their authentication devices across heterogeneous environments. Typical use cases include deploying hardware tokens to employees who require strong two-factor authentication, provisioning FIDO2 security keys for secure access to web services and corporate systems, managing PIV credentials for compliance-driven environments, and maintaining OpenPGP keys stored on dedicated hardware. By consolidating these administrative tasks into one tool, the publisher's offering helps reduce the complexity that often accompanies the adoption of hardware-based authentication. The project is distributed openly through the publisher's GitHub presence at github.com/framefilter, reflecting a development model that emphasizes transparency, community visibility, and accessibility for users who prefer to inspect and build software from source.
