Warp introduces new dynamic environment variables that allow users to load keys or secrets from external managers like 1Password or LastPass into their terminal sessions at runtime, reducing interruptions in the development workflow. This feature enables accessing tokens needed for authentication without storing them in local .env files. Dynamic environment variables streamline the process of accessing secrets and authenticating into different development environments without switching contexts. Users can create named, templated commands to pull environment variables through CLI or API for an external management service at runtime. Static environment variables are also available for non-sensitive variables like HOST endpoints.
