Short defensive post on the Alpine openssh-server password authentication bypass fixed on 2026-11-05: who is affected (four conditions), how to check a host or every container, the fix and why sshd needs a restart, the workaround, the tiny-cloud alpine user, and what to look for in logs.

Companion repo: The-DevOps-Daily/alpine-sshd-check (private until this merges). Its outputs were recorded on throwaway Alpine 3.21 to 3.24 and edge containers with sshd on --network none.
