Two intertwined bugs reported in #427 by @iSchumi6210: 1. Login silently fails over HTTP. Backend defaulted COOKIE_SECURE to true when NODE_ENV=production. Over plain HTTP the browser drops the Secure cookie → next /auth/session request returns 401 → redirect back to /admin/login → no error shown. picpeak-setup.sh writes NODE_ENV=production but never writes COOKIE_SECURE, so every first-time install without a reverse proxy hits this. 2. Admin password is generated but admins can't find it. The 001_init.js migration writes the generated password to data/ADMIN_CREDENTIALS.txt inside the backend container, but picpeak-setup.sh only copies it out when --reset-admin-password is passed. Default-path users never see it and resort to manual bcrypt updates in psql. Changes: - tokenUtils.js: production default goes from `true` to `'auto'`. On real HTTPS req.secure is true → Secure flag is still emitted (no security regression for reverse-proxy deployments). On plain HTTP req.secure is false → Secure flag omitted → login works. Users who explicitly want the strict HTTPS-only behaviour can still set COOKIE_SECURE=true. - .env.example: rewrite the COOKIE_SECURE block to make the new default obvious and explain when to override (set =true for strict, =false to skip the per-request check, leave unset for the auto behaviour). - picpeak-setup.sh (both Docker and native paths): - Write COOKIE_SECURE=auto explicitly to the generated .env (defense in depth so the right behaviour is preserved even if the backend default flips again later) - After migrations, ALWAYS copy ADMIN_CREDENTIALS.txt out of the backend container/data dir to the host data dir, chmod 600, and print the email + password to the install output. The credentials file remains as a backup record that the operator should delete after noting the password. Verified locally with all 4 permutations of NODE_ENV × COOKIE_SECURE: production, unset → HTTPS: secure=true ✓ HTTP: secure=false ✓ (was both true) production, =true → both: secure=true (strict opt-in preserved) production, =auto → HTTPS: secure=true HTTP: secure=false (already-correct) development, unset → both: secure=false (dev unchanged)
