How to Secure Your Turso App
Last updated: January 12, 2026
Turso provides edge SQLite databases with libSQL. This guide covers securing your Turso-powered applications.
Step-by-Step Security Guide
1. Protect Auth Tokens
Store Turso auth tokens in environment variables. Never commit them to repositories.
# Use environment variables
TURSO_DATABASE_URL=libsql://...
TURSO_AUTH_TOKEN=...2. Use Read-Only Tokens Where Possible
For read-only operations, use read-only tokens to limit potential damage from token exposure.
3. Implement Application-Level Access Control
Turso is SQLite-based and lacks RLS. Implement access control in your application layer.
4. Use Parameterized Queries
Prevent SQL injection by using parameterized queries with the libSQL client.
await db.execute({
sql: 'SELECT * FROM users WHERE id = ?',
args: [userId]
});5. Secure Embedded Replicas
If using embedded replicas, ensure the SQLite file location is secured and not accessible via web.
6. Scan Your Application
Run VAS to verify your deployed application handles database access securely.

Ready to Secure Your App?
Security is an ongoing process, not a one-time checklist. After implementing these steps, use VAS to verify your Turso app is secure before launch, and consider regular scans as you add new features.
Frequently Asked Questions
Does Turso have Row Level Security?
No, Turso uses libSQL (SQLite-compatible) which doesn't have RLS. Implement access control in your application layer, filtering queries based on authenticated user.
How do I secure edge replicas?
Edge replicas use the same auth token as primary. Turso handles replication security. Your responsibility is protecting the token and implementing proper access control.
