Store secrets in a proper manager. 1Password and Doppler both have solid secrets management with fine-grained access control. Worth noting: Bitwarden's own npm CLI was compromised via a hijacked GitHub Action in their CI pipeline in April 2026 - end-user vaults were untouched, but it's a clean illustration of why the tool you trust and the channel it ships through are separate threat surfaces. - Source: dev.to / 3 months ago
1Password has a Secrets Automation product that allows teams to reference secrets stored in their 1Password vaults from CI/CD pipelines, Docker environments, and application configurations. The op CLI tool resolves secret references at runtime, substituting vault values into configuration at the point of use. - Source: dev.to / 4 months ago
