Secrets and configuration
Never commit API keys or database passwords; use environment variables and secret managers in production.
Rotate keys when team members leave or repos change visibility.
Separate development, staging, and production credentials; staging should not use production data without masking.
Authentication and authorization
Use battle-tested auth providers or libraries; do not store passwords in plain text, ever.
Enforce HTTPS everywhere; set secure cookie flags and sensible session timeouts.
Check authorization on every server route, not only in the UI, clients can be modified.
Data handling
Collect only data you need; document retention and deletion in your privacy policy.
Validate and sanitize inputs server-side; parameterized queries prevent SQL injection.
Back up databases automatically and test restores before you need them in a crisis.
Monitoring and response
Log authentication failures and unusual API patterns; alert on error rate spikes.
Have a simple incident contact path, even a one-page runbook helps.
