Authy — Secure Secret Injection

Inject secrets into subprocesses as environment variables. You never see, handle, or log secret values.

How It Works

Your token is run-only. You can discover secret names with authy list and inject them into subprocesses with authy run. You never see secret values directly.

Inject Secrets into a Command

authy run --scope <policy> --uppercase --replace-dash '_' -- <command> [args...]

The --uppercase --replace-dash '_' flags turn secret names like db-host into env vars like DB_HOST.

Examples:

authy run --scope deploy --uppercase --replace-dash '_' -- ./deploy.sh
authy run --scope backend --uppercase --replace-dash '_' -- node server.js
authy run --scope testing --uppercase --replace-dash '_' -- pytest

Discover Secret Names

authy list --scope <policy> --json

Output: {"secrets":[{"name":"db-host","version":1,...}]}

Write Scripts That Use Secrets

Write code that reads environment variables, then run it with authy run:

cat > task.sh << 'EOF'
#!/bin/bash
curl -H "Authorization: Bearer $API_KEY" https://api.example.com/data
EOF
chmod +x task.sh
authy run --scope my-scope --uppercase --replace-dash '_' -- ./task.sh

Error Codes

Rules

• Only use authy run and authy list — these are the only commands available to you
• Never hardcode credentials — reference env vars, run via authy run
• Never echo, print, or log env vars in subprocess scripts — secrets exist in memory only
• Never redirect env vars to files — do not write $SECRET to disk
• Use --scope to limit access to needed secrets only
