How to Secure Your Claude Code App
Last updated: January 12, 2026
Claude Code assists development through conversation, but the code it generates needs security review. This guide covers securing Claude Code-assisted projects.
Step-by-Step Security Guide
1. Review Security-Critical Code
Never auto-accept Claude's suggestions for authentication, authorization, or data handling without careful review.
2. Keep Secrets Out of Prompts
Never paste API keys, passwords, or credentials into your conversation. Claude may incorporate them into suggestions.
3. Use Established Libraries
For authentication and encryption, ask Claude to use established libraries rather than custom implementations.
4. Request Security Best Practices
Explicitly ask Claude to follow security best practices when generating sensitive code.
// Good prompt: "Implement user auth using bcrypt for password hashing and secure session management"5. Verify Database Security
If Claude generates database code, verify RLS policies and parameterized queries are used correctly.
6. Scan Before Deployment
Run VAS on your deployed application to catch any security issues in the generated code.
