Too many secrets (2ms) is an open source CLI tool, powered by Checkmarx, that enables you to identify sensitive data such as secrets, authentication keys and passwords that are stored in your system in unencrypted text. This tool supports scanning of internal communication platforms (Slack, Discord), content management (Confluence, Paligo) and source code storage locations (Git repo, local directory).
This application is written in Go language and is based on the framework provided by gitleaks.
The tool checks the content using a series of rules that are designed to identify a wide range of sensitive items such as AWS access token, Bitbucket Client ID, GitHub PAT etc. For a complete list of rules, see docs/list-of-rules.md.
Additionally, the tool incorporates a scoring system based on the Common Vulnerability Scoring System (CVSS) to help prioritize remediation efforts.
The following sections explain how to install 2ms using the following methods:
- Download and Install Precompiled Binaries
- Compile from Source
- Run From Docker Container
- CI/CD Integrations
You can download 2ms precompiled binaries for amd64 architecture from our releases page.
The following links can be used to download the "latest" version, for each supported OS.
Install 2ms globally on your local machine by placing the compiled binary on your path. For example, on Linux you can place 2ms binary in /usr/local/bin/ or create a symbolic link.
Example:
cd /opt
mkdir 2ms
cd 2ms
wget https://github.com/checkmarx/2ms/releases/latest/download/linux-amd64.zip
unzip linux-amd64.zip
sudo ln -s /opt/2ms/2ms /usr/local/bin/2ms
You can compile the project from its source using the following commands:
git clone https://github.com/checkmarx/2ms.git
cd 2ms
go build -o dist/2ms main.go
./dist/2msWe publish container image releases of 2ms to checkmarx/2ms .
To run 2ms from a docker container use the following command:
docker run checkmarx/2ms
You can also mount a local directory by using the-v flag with the following syntax -v <local-dir-path>:<container-dir-path>
Example:
docker run -v /home/user/workspace/git-repo:/repo checkmarx/2ms git /repo- For
gitcommand, you need to mount your git repository to/repoinside the container
The following is a template for creating a GitHub Action that runs 2ms from a Docker image to scan your GitHub repo.
Note: Make sure that in the actions/checkout step you access the full history by setting the depth as follows fetch-depth: 0

run: docker run -v $(pwd):/repo checkmarx/2ms:2.8.1 git /repo- This example uses version to
2.8.1of 2ms. Make sure to check for the latest version. - 💡 Take a look at 2ms GitHub Actions pipeline as 2ms scans itself using 2ms.
To use 2ms in Azure DevOps Pipeline, create a new pipeline (see this tutorial for getting started with Azure DevOps Pipelines). Then, use the following template to create a yml file azure-pipelines.yml to run 2ms:
trigger:
- master
pool:
vmImage: ubuntu-latest
steps:
- script: docker run -v $(pwd):/repo checkmarx/2ms:2.8.1 git /repo
displayName: Run 2ms- This example uses version to
2.8.1of 2ms. Make sure to check for the latest version.
2ms has dedicated commands for scanning each of the supported platforms. To run a scan, you need to enter the command for the platform that you are scanning, along with all of the arguments that are relevant for that platform. The scan command arguments are used for authentication as well as to provide details about the locations that will be scanned. These arguments differ for each platform. In addition, you can add global flags to customize the scan configuration.
The fundamental structure of a scan command is:
2ms <scan command> [scan command arguments] [global flags]
Scan command arguments and global flags can be passed either as flags in the scan command or via a config file.
We've built the 2ms command line interface to be as self-descriptive as possible. This is the help message that is shown when you execute 2ms without args:

Scan Commands
confluence Scan Confluence server
discord Scan Discord server
filesystem Scan local folder

paligo Scan Paligo instance
slack Scan Slack team
Additional Commands:
completion Generate the autocompletion script for the specified shell
help Help about any command
rules List all rules
Flags:
--add-special-rule strings special (non-default) rules to apply.
This list is not affected by the --rule and --ignore-rule flags.
--allowed-values strings allowed secrets values to ignore
--config string config file path
-h, --help help for 2ms
--ignore-on-exit ignoreOnExit defines which kind of non-zero exits code should be ignored
accepts: all, results, errors, none
example: if 'results' is set, only engine errors will make 2ms exit code different from 0 (default none)
--ignore-result strings ignore specific result by id
--ignore-rule strings ignore rules by name or tag
--log-level string log level (trace, debug, info, warn, error, fatal) (default "info")
--max-target-megabytes int files larger than this will be skipped.
Omit or set to 0 to disable this check.
--regex stringArray custom regexes to apply to the scan, must be valid Go regex
--report-path strings path to generate report files. The output format will be determined by the file extension (.json, .yaml, .sarif)
--rule strings select rules by name or tag to apply to this scan
--stdout-format string stdout output format, available formats are: json, yaml, sarif (default "yaml")
--validate trigger additional validation to check if discovered secrets are valid or invalid
-v, --version version for 2ms
Use "2ms [command] --help" for more information about a command.
You can pass --config [path to config file] argument to specify a configuration file. The configuration file format can be YAML or JSON.
Example:
log-level: info
regex:
- password\=
report-path:
- ./report.yaml
- ./report.json
- ./report.sarif
paligo:
instance: your-instance
username: your-usernameYou can pass a combination of command line arguments and a configuration file. In this case, the 2ms merges the values from the file and the explicit arguments.

| --validate | Trigger additional validation to check if discovered secrets are valid or invalid. SEE BELOW | ||
| -v, --version | Version of 2ms that is running. |
Adding the --validate flag checks the validity of the secrets found. For example, if a Github token is found, it will check if the token is valid by making a request to the Github API. We will use the least intrusive method possible to check the validity of the secret.
The list of services that support the Validity Check feature can be found in the List of Rules document.
The result of the validation can be:
valid- The secret is validinvalid- The secret is invalidunknown- We failed to check, or we are not checking the validity of the secret at all
If the --validate flag is not provided, the validation field will be omitted from the output, or its value will be an empty string.
Note: The validity check also impacts the score field. If the flag is not provided, the validity is assumed to be "unknown" in the score formula.
Special rules are rules that are configured in 2ms but are not run as part of the default ruleset, usually because they are too noisy or too specific. You can use the --add-special-rule flag to add special rules by rule ID.
For example:
2ms git . --add-special-rule hardcoded-password| Rule ID | Description |
|---|---|
hardcoded-password |
Detects strings that are assigned to variables that contain the word password, access, key, etc. |
You may specify one or more custom regex rules with the optional argument --regex. The value provided will be parsed as a regular expression and will be matched against the target items.
my-file.txt
password=1234567
username=admin2ms filesystem --path . --regex username= --regex password=
2ms is extendable with the concept of plugins. We designed it like this so anyone can easily contribute, improve and extend 2ms. Read more about contributing in our CONTRIBUTING.md file.
