    When you Dockerize a .NET app, special characters in passwords — especially the dollar sign ($) — can cause authentication to fail due to Linux-style variable substitution in .env files. This article walks through the root cause, explains how Docker and PowerShell handle escaping differently, and shares best practices for managing credentials safely across platforms. The fix? Escape $ as $$, validate before deployment, and use Docker Secrets in production. A small syntax tweak can save you hours of debugging.
