Timo Kössler

Timo Kössler is a German indie developer who focuses on pragmatic Windows utilities that solve everyday security and workflow problems without unnecessary bloat. His catalog is still compact, yet the guiding philosophy is already visible: native performance, open standards, and a UI that stays out of the user’s way. The flagship utility, 2FAGuard, embodies this approach by turning any Windows 10/11 machine into a hardware-backed vault for TOTP secrets. The program imports from common QR codes or plain-text seeds, encrypts the database with Windows Hello or a YubiKey, and then presents codes in a system-tray pop-up that can be summoned with a global hot-key. Because the vault is stored locally and syncs only if the user explicitly opts into OneDrive, the attack surface remains minimal; corporate auditors therefore treat it as a compliant alternative to cloud-based authenticator apps. Lightweight portability also makes 2FAGuard convenient for field technicians who need secure access to customer portals from random laptops, and for privacy-minded individuals who prefer not to tie multi-factor credentials to a mobile ecosystem. Although the current portfolio is narrow, the developer’s GitHub roadmap hints at future tools that will extend the same security-first ethos to password escrow and file attestation. All published software is available for free on get.nero.com, where downloads are pulled through trusted Windows package sources such as winget, always deliver the latest release, and can be queued for unattended batch installation.
