Are you still keeping API tokens in ~/.secrets? Any app you install can read them. ykvault encrypts every secret with a YubiKey challenge-response key — each get/set requires a physical touch, and the encrypted files are useless without your key.
A working guide to using a YubiKey for SSH on a real Linux fleet — the four knobs (resident, touch, PIN, agent), a four-mode policy for root and Ansible, software-only alternatives, and where SSH CAs fit in.
180 accounts are breached every second — and most of it comes down to reused passwords and missing MFA. A look at the software quality collapse behind the headlines, and why the fix is the same infrastructure-level move HTTPS once made: passkeys, on-device DLP, and capability-scoped AI agents.
A post-mortem of intermittent HTTPS failures across a mobile proxy fleet: TLS 1.3 handshakes silently dying on memory-starved Android devices — large multi-packet handshake messages, inflated by post-quantum key shares, stressing proxy buffers under memory pressure.
