Eliminates plaintext credential storage while maintaining compatibility with bash-based tools through a file-bridge architecture. ### Prerequisites The keyring Python library must be installed for each Python version that will access secrets: pip3 install keyring # If multiple Python versions exist (common on macOS): /usr/bin/python3 -m pip install keyring /opt/homebrew/opt/python@3.14/bin/python3.14 -m pip install --break-system-packages keyring ### Check Keychain Health Verify the keychain bridge is working correctly: python3 -c " import keyring # Test write keyring.set_password('keychain-bridge-test', 'test', 'hello') # Test read val = keyring.get_password('keychain-bridge-test', 'test') assert val == 'hello', f'Read back {val!r}, expected hello' # Cleanup keyring.delete_password('keychain-bridge-test', 'test') print('Keychain health: OK') " If this fails, see Diagnose Issues below. ### Migrate Secrets Migrate plaintext secret files to macOS Keychain. The migration tool: Auto-detects all Python versions on the system Injects each secret from ALL detected Python binaries (required for ACL coverage) Verifies the round-trip read Optionally deletes the original file python3 SKILL_DIR/scripts/migrate_secrets.py --dir ~/.openclaw/secrets/ --account moltbot --dry-run # Remove --dry-run to actually migrate python3 SKILL_DIR/scripts/migrate_secrets.py --dir ~/.openclaw/secrets/ --account moltbot After migration, secrets fall into two groups: ### Group A — Keychain Only Python scripts read directly via keychain_helper.get_secret(service). No file on disk. ### Group B — File Bridge Bash scripts cannot reliably use Python keyring as a subprocess (see Known Issues). For these, a boot-time bridge script populates files from the keychain: # Add to your LaunchAgent or startup script: bash SKILL_DIR/scripts/populate_secrets.sh This reads each Group B secret from keychain and writes it to a chmod 600 file that bash scripts can cat. ### From Python import sys, os sys.path.insert(0, os.path.dirname(os.path.abspath(__file__))) from keychain_helper import get_secret token = get_secret("my-service-name") The helper tries keychain first, falls back to file read. ### From Bash (via Group B file) MY_SECRET=$(cat ~/.openclaw/secrets/my-service-name) Ensure the service is listed in populate_secrets.sh so the file is populated at boot. ### From Bash (via CLI helper — interactive only) # Works from terminal, but HANGS from LaunchAgent bash scripts MY_SECRET=$(python3 path/to/get_secret.py my-service-name) ### Write a Secret Critical: Inject from ALL Python versions on the system. Keychain ACLs are per-binary — an item created by Python 3.9 cannot be read by Python 3.14 unless both binaries are in the ACL. # Detect Python versions PYTHONS=() [ -x /usr/bin/python3 ] && PYTHONS+=(/usr/bin/python3) [ -x /opt/homebrew/opt/python@3.14/bin/python3.14 ] && PYTHONS+=(/opt/homebrew/opt/python@3.14/bin/python3.14) # Inject from each for py in "${PYTHONS[@]}"; do $py -c "import keyring; keyring.set_password('SERVICE', 'ACCOUNT', 'VALUE')" done Or use the migration tool for batch operations. ### Audit for Leaks Check for unexpected plaintext secret files and verify keychain health: python3 SKILL_DIR/scripts/audit_secrets.py --dir ~/.openclaw/secrets/ --account moltbot Reports: Unexpected files in the secrets directory (potential leaks) Keychain items that exist but can't be read (ACL issues) Files that exist but aren't in keychain (unmigrated) Keychain library installation status per Python version ### security find-generic-password -w hangs macOS Tahoe 26.x regression. The security CLI hangs indefinitely (or returns exit code 36) when reading keychain items, even after security unlock-keychain. This affects ALL CLI-based keychain reads. Fix: Use Python keyring library instead. It uses the Security framework C API via ctypes, bypassing the broken CLI entirely. ### Python keyring returns None or raises errSecInteractionNotAllowed (-25308) This happens when running from an SSH session. The keychain requires a GUI session (SecurityAgent) context. Fix (recommended): Use the Group B file-bridge pattern. Write secrets from a GUI session (LaunchAgent or VNC Terminal), then read from chmod 600 files in SSH. Fix (SSH write — ctypes unlock): The security unlock-keychain -p CLI command is also broken on Tahoe (returns "incorrect passphrase" with correct password). Use the Security framework C API via ctypes instead. The unlock + set + verify must happen in a single Python process — the unlock does not persist across invocations: python3 << 'PYEOF' import ctypes, ctypes.util, keyring # Unlock via Security framework (bypasses broken security CLI) Security = ctypes.cdll.LoadLibrary(ctypes.util.find_library("Security")) keychain = ctypes.c_void_p() path = b"/Users/USERNAME/Library/Keychains/login.keychain-db" Security.SecKeychainOpen(path, ctypes.byref(keychain)) pw = b"YOUR_LOGIN_PASSWORD" Security.SecKeychainUnlock(keychain, ctypes.c_uint32(len(pw)), pw, ctypes.c_bool(True)) # Now keyring works — but ONLY within this same process keyring.set_password("SERVICE", "ACCOUNT", "VALUE") print("OK" if keyring.get_password("SERVICE", "ACCOUNT") else "FAIL") PYEOF Caveats of ctypes unlock: Unlock is process-scoped — a second python3 invocation starts locked again Only /usr/bin/python3 (Apple system Python) can write after ctypes unlock; Homebrew Pythons (3.12, 3.14) still get -25308 even in the same process For multi-Python ACL coverage, write from /usr/bin/python3 first, then inject from other Pythons in a VNC Terminal session (GUI context) If you need SSH-only access to the secret after writing, create a Group B bridge file in the same process: # After keyring.set_password() succeeds in the same process: import os val = keyring.get_password("SERVICE", "ACCOUNT") os.makedirs(os.path.expanduser("~/.my-app/secrets"), exist_ok=True) path = os.path.expanduser("~/.my-app/secrets/SERVICE") with open(path, "w") as f: f.write(val) os.chmod(path, 0o600) ### Python keyring hangs when called from bash LaunchAgent Novel finding (macOS Tahoe 26.x). When a bash script is the LaunchAgent program and spawns python3 get_secret.py as a subprocess, the Python process hangs indefinitely. The SecurityAgent session attachment is lost in the bash-to-python subprocess transition. Fix: Use the Group B file-bridge pattern. Have a Python-native process populate files at boot, then bash scripts read from files. Alternatively, make Python the direct LaunchAgent program (not a subprocess of bash). ### Different Python versions can't read each other's items Keychain ACLs are per-binary. An item created by /usr/bin/python3 (Python 3.9) has an ACL entry only for that binary. /opt/homebrew/bin/python3.14 is a different binary and gets access denied. Fix: Inject from both Python versions: # Read from working version, write via target version import subprocess, keyring value = keyring.get_password("service", "account") subprocess.run(["/opt/homebrew/bin/python3.14", "-c", f"import keyring; keyring.set_password('service', 'account', '{value}')"]) Or use migrate_secrets.py which handles this automatically. ### keyring not installed for a Python version Each Python binary has its own site-packages. pip3 install keyring only installs for one. # Check which Python pip3 targets pip3 --version # Install for system Python /usr/bin/python3 -m pip install keyring # Install for Homebrew Python /opt/homebrew/opt/python@3.14/bin/python3.14 -m pip install --break-system-packages keyring ### Architecture Reference ┌─────────────────────┐ │ macOS Keychain │ │ (login keychain) │ └──────────┬──────────┘ │ ┌────────────────┼────────────────┐ │ │ │ ┌─────────▼─────────┐ │ ┌──────────▼──────────┐ │ Group A │ │ │ Group B │ │ (keychain only) │ │ │ (file bridge) │ │ │ │ │ │ │ Python scripts │ │ │ populate_secrets.sh │ │ import keychain_ │ │ │ runs at boot → │ │ helper.get_secret()│ │ │ writes chmod 600 │ │ │ │ │ files for bash │ └────────────────────┘ │ └──────────────────────┘ │ ┌──────────▼──────────┐ │ Fallback │ │ get_secret() tries │ │ keychain first, │ │ then file read │ └─────────────────────┘ ### When to use Group A The consumer is a Python script The script runs as a LaunchAgent (or from terminal) The script is NOT spawned as a subprocess from a bash LaunchAgent ### When to use Group B The consumer is a bash script The bash script runs as a LaunchAgent The secret is referenced by a config file that expects file:secrets/ paths ### Known Issues (macOS Tahoe 26.x) security CLI broken across the board: find-generic-password -w hangs or exits 36. unlock-keychain -p returns "incorrect passphrase" with correct password. show-keychain-info exits 36. The entire security CLI is unreliable on Tahoe — use Python keyring (Group A) or ctypes Security framework for all keychain operations. Keychain ACL per-binary: Must inject from every Python version that will read the item. Bash subprocess loses SecurityAgent: bash LaunchAgent → python3 subprocess hangs. Use Group B file bridge. SSH sessions lack GUI context: Keychain reads/writes fail with -25308. Use ctypes SecKeychainUnlock in the same Python process (see Diagnose Issues), or use Group B file bridge. The ctypes unlock is process-scoped — it does not persist across separate command invocations. keyring must be installed per-Python: Each binary's site-packages is independent. Homebrew Python ignores ctypes unlock: After SecKeychainUnlock via ctypes, /usr/bin/python3 (Apple system Python 3.9) can read/write via keyring, but Homebrew Pythons (3.12, 3.14) still get -25308. Root cause unknown — may be entitlement or codesigning difference. Workaround: write from /usr/bin/python3, then inject from Homebrew Pythons in a GUI session (VNC Terminal or LaunchAgent). These issues are specific to macOS Tahoe 26.x (macOS 26). Earlier versions (Sonoma 14, Sequoia 15) may not exhibit all of them, but the Group A/B architecture is safe on all versions. ### External Endpoints None. This skill makes zero network requests. All operations are local to the macOS Keychain and filesystem. ### Security & Privacy All operations execute locally against the macOS login keychain No telemetry, analytics, or usage tracking No data leaves the machine under any circumstances Scripts request no network permissions Secrets are only read from and written to the local keychain or chmod 600 files Migration tool never logs or displays secret values ### Trust Statement All code is open for inspection — no obfuscation, no minification, no compiled binaries. The skill operates exclusively on the local macOS Keychain and filesystem. Built and tested on a production Mac Mini M4 Pro deployment running OpenClaw 24/7 with 12+ API keys and 25 automated scripts. ## Trust - Source: tencent - Verification: Indexed source record - Publisher: Euda1mon1a - Version: 1.1.0 ## Source health - Status: healthy - Item download looks usable. - Yavira can redirect you to the upstream package for this item. - Health scope: item - Reason: direct_download_ok - Checked at: 2026-04-29T07:32:24.632Z - Expires at: 2026-05-06T07:32:24.632Z - Recommended action: Download for OpenClaw ## Links - [Detail page](https://openagent3.xyz/skills/keychain-bridge) - [Send to Agent page](https://openagent3.xyz/skills/keychain-bridge/agent) - [JSON manifest](https://openagent3.xyz/skills/keychain-bridge/agent.json) - [Markdown brief](https://openagent3.xyz/skills/keychain-bridge/agent.md) - [Download page](https://openagent3.xyz/downloads/keychain-bridge)
