This feature is part of [Mobile DevOps](../mobile_devops.md) developed by [GitLab Incubation Engineering](https://about.gitlab.com/handbook/engineering/incubation/).
You can securely store up to 100 files for use in CI/CD pipelines as secure files. These files are stored securely outside of your project's repository and are not version controlled. It is safe to store sensitive information in these files. Secure files support both plain text and binary file types but must be 5 MB or less.
To use your secure files in a CI/CD job, you must use the [`download-secure-files`](https://gitlab.com/gitlab-org/incubation-engineering/mobile-devops/download-secure-files)
