## Permission Explanation
|
|
|
|
### Percona/MySQL/MariaDB Permissions
|
|
|
|
When creating a user, you can select databases to grant permissions:
|
|
|
|
- Select specific databases: User can only access selected databases
|
|
- No selection: User has no database permissions
|
|
|
|
### PostgreSQL Permissions
|
|
|
|
PostgreSQL permission management is more fine-grained. You can set different permissions for databases, schemas, tables, etc. The panel only supports granting database access permissions.
|
|
|
|
## Password Security
|
|
|
|
- Use strong passwords containing uppercase and lowercase letters, numbers, and special characters
|
|
- Password length recommended 16 characters or more
|
|
- Use different database users for different applications
|
|
- Change passwords regularly
