1Password simplifies secure app development by replacing hardcoded .env files with secure references to cloud-stored secrets via their CLI and SDKs. The migration process involves installing the 1Password VS Code plugin, creating shared vaults for secrets, and accessing these secrets programmatically using SDKs. Users can organize and share secrets securely, rotate keys easily, and ensure sensitive information isn't stored in version history or hardcoded files. The transition enhances security and management of application configurations.
