You can now add sensitive Environment Variables to your projects for added security of secret values like API keys.

While all Environment Variables are encrypted, **sensitive values can** **only be decrypted during builds**. This replaces our legacy secrets implementation [which is being sunset](https://vercel.com/changelog/legacy-environment-variable-secrets-are-being-sunset).

Get started using [Sensitive Environment Variables](https://vercel.com/docs/projects/environment-variables/sensitive-environment-variables) through the dashboard or with Vercel CLI `33.4`.
