Cause (Documented platform behavior): The default admin/admin password is no longer used; a strong initial admin password must be supplied.
Fix status: documented_behavior
Misleading approaches:
- Using admin:admin from older tutorials.
Limitations:
- Source/docs-derived; not reproduced.
Evidence (public sources, summarized; not reproduced by this contributor):
- https://raw.githubusercontent.com/opensearch-project/security/c5cf7f0315b19d5ebe29c03003f26607d0fa0305/src/main/java/org/opensearch/security/tools/democonfig/SecuritySettingsConfigurer.java (official_docs, unknown, documented_behavior): Demo config reads OPENSEARCH_INITIAL_ADMIN_PASSWORD; validates it (regex upper/lower/digit/special, min length, strong) and exits with 'Password %s failed validation ...' or exits with 'No custom admin password found. Please provide a password via the environment variable %s.' if empty.

Search phrasings: No custom admin password found OPENSEARCH_INITIAL_ADMIN_PASSWORD; opensearch docker 2.12 admin password required; opensearch initial admin password failed validation

Problem details
- Observed symptom
- Demo security setup aborts and the container exits during startup.
- Context
- Product: OpenSearch security plugin demo configuration Component: install_demo_configuration (docker entrypoint) Operation: docker run opensearchproject/opensearch (or compose from old tutorials) without OPENSEARCH_INITIAL_ADMIN_PASSWORD, or with 'admin'/simple passwords Affected versions: unknown Environment: unknown Packages: opensearchproject/opensearch >=2.12 Trigger: Demo configuration requires a custom admin password from the env var and validates strength (min length, upper/lower/digit/special, zxcvbn strong).

Proposed fix: [OpenSearch >= 2.12 Docker] container exits: 'No custom admin password found. Please provide a password via the environment variable OPENSEARCH_INITIAL_ADMIN_PASSWORD.' (or 'Password ...
Recommended action: Set OPENSEARCH_INITIAL_ADMIN_PASSWORD to a strong password (8+ chars incl. upper, lower, digit, special) in the container env; alternatively disable the demo config/security plugin for local-only tests (DISABLE_INSTALL_DEMO_CONFIG / DISABLE_SECURITY_PLUGIN).
Option: Provide a strong initial admin password [evidence: official_recommended_action]
Applies when: See record scope.
Steps:
1. docker run -e OPENSEARCH_INITIAL_ADMIN_PASSWORD='<Strong#Pass123>' -e discovery.type=single-node opensearchproject/opensearch
Expected: Command proceeds without the error.
