Principal Cybersecurity Architect · Germany
Yes, FiraSenax means something – my name, protected by industrial-grade ROT13. Security by obscurity: please don't tell anyone.
I work on security architecture – identity, authentication and how systems hold up when real people use them. In my spare time I build small tools that make security, and the house, a little easier to live with.
KeyMelier – the sommelier for your security keys. A free desktop app for macOS, Windows and Linux that checks FIDO2 security keys from any vendor (authenticity, known vulnerabilities), shows which accounts depend on which key, and helps with backups and lost keys. It is young – if you have a security key, I would be glad about a test report or an issue.
The house runs on Home Assistant – after many years on ioBroker I switched sides. I keep forks of the integrations I use, such as Dreame robot vacuums and lawn mowers.
Handball. I write match reports and cut highlight videos for our youth teams – and automate the tedious parts where I can.
Topics I care about: passkeys & FIDO2 · security architecture · privacy by default · tools that tell the truth about what they checked.
