PlanetScale Security Best Practices
Scoped passwords per environment, deploy-request branching, web console role restrictions. The 6 PlanetScale practices that actually reduce risk — and the misconfigurations vibe-coded apps keep shipping.
Verify your app follows these best practices automatically.
PlanetScale is serverless MySQL with branching, deploy requests, and Vitess sharding underneath. The defaults are reasonable, but most teams still ship with admin-scoped connection strings in environment variables, single passwords across all environments, and unrestricted web console access. These 6 practices fix the highest-impact gaps — start with scoped passwords if you're only doing one.

Security Best Practices
#1Use Scoped Passwords
criticalCreate connection passwords with minimal permissions. Don't use admin passwords in applications.
Implementation
Create branch-specific passwords with read/write restrictions as needed
#2Store Connection Strings Securely
criticalConnection strings contain credentials. Use environment variables, never commit to code.
Implementation
Set DATABASE_URL as environment variable in your deployment platform
#3Use Safe Migrations
highDeploy schema changes safely using PlanetScale's branch and deploy request workflow.
Implementation
Create branches for schema changes, use deploy requests for production
#4Enable Web Console Restrictions
highRestrict who can access the database through PlanetScale's web console.
Implementation
Configure organization roles, limit console access to necessary team members
#5Use Separate Passwords per Environment
highCreate different connection passwords for development, staging, and production.
Implementation
Generate new passwords for each environment, store in environment variables
#6Enable Query Insights
mediumMonitor queries for performance issues and potential security concerns.
Implementation
Review Query Insights for unusual patterns or slow queries
Common Mistakes to Avoid
Admin password in application code
Admin passwords have full access if compromised
Create scoped passwords with minimal permissions
Direct schema changes in production
Can cause downtime or data issues
Use branch and deploy request workflow for all schema changes
Same password across environments
One compromised environment exposes others
Generate separate passwords for each environment

Is PlanetScale secure?
Yes, PlanetScale is used by major companies. Security depends on using scoped passwords, storing credentials properly, and using their safe migration workflow.
How do I safely change my schema?
Create a branch, make schema changes, create a deploy request, and merge to production. PlanetScale handles the migration safely with no downtime.
Can I restrict database access by IP?
PlanetScale uses credential-based authentication rather than IP restrictions. Use scoped passwords and organization roles to control access.
