+# Email accounts
+
+`/account` offers registration, password login, email verification/resend, and logout.
+`/api/account/session` returns the current account; other actions use same-origin POST.
+Passwords require at least 12 characters and at most 256 UTF-8 bytes. Only verified
+accounts can log in. Verification links expire after 30 minutes and are consumed once.
+Session tokens expire after seven days; logout deletes the current token immediately.
+Only token SHA-256 digests are stored. Passwords use individually salted scrypt.
+
+## Runtime configuration
+
+The existing production deployment reads `/etc/prompt.env` on ces-control. Set its
+ownership to root and mode to 0600. The operator should update SMTP_PASSWORD there
+through a secure remote session, without putting it in command arguments, repository,
+CI output, release.env, or chat. Existing compose deployment reads this file without
+copying credentials into the release directory. Do not run `docker compose config`
+without `--quiet` against the production environment because interpolation shows secrets.
+Docker administrators can inspect container environment; access to Docker is privileged.
+
+Set ACCOUNT_PUBLIC_ORIGIN to the exact browser origin and SMTP_HOST=smtpdm.aliyun.com,
+SMTP_PORT=465, SMTP_USERNAME and SMTP_FROM=noreply@notice.entroia.com. TLS certificate
+validation stays enabled. Missing SMTP configuration returns a generic service failure;
+resend with the registration password can recover an account whose initial delivery failed.
+
+Keep AUTH_CONFIG_FILE configured for administrator access. Missing administrator
+configuration fails closed. AUTH_DISABLED_FOR_TESTS is false by default and is enabled
+only by the disposable legacy integration stack; never enable it in production.
+Email account cookies never satisfy administrator authorization. With the current HTTP
+acceptance origin use AUTH_COOKIE_SECURE=false; use true after enabling HTTPS.
+
+Limits persist in PostgreSQL: 10 logins and 3 registration/resend attempts per email per
+15 minutes, plus 300 requests per 15 minutes globally. ACCOUNT_TRUST_PROXY defaults
+false. Enable it only when a trusted ingress overwrites x-forwarded-for; this changes
+the global cap to 60 per trusted client address. Do not enable it on the direct public port.
+Limits count failures and successes. Registration/resend always give the same success
+response for existing/unknown emails, and login uses a dummy KDF for unknown accounts.
+The rate limit itself can reveal recent activity for a known email; it does not reveal
+whether an account exists. No password recovery or account deletion is included.
+
+## Verification
+
+ces-control runs crypto/origin tests, PostgreSQL verification-token replay races,
+expired/revoked sessions, concurrent limit consumption and unverified login rejection.
+Production-auth exercises verify that account cookies cannot authorize legacy writes.
+Actual SMTP delivery and visual acceptance at http://8.211.154.134:18131/account require
+operator runtime configuration and the normal manually approved deployment.
