# Multi origin CodeCommit and tools
As a developer working in a large enterprise or for a group that supports multiple products, you may often find yourself accessing Git repositories from different organizations. Currently, to securely access multiple Git repositories in other popular tools, you need SSH keys, GPG keys, a Git credential helper, and a significant amount of setup by the developer hoping to commit to the repository. In addition, administrators must be aware of the various ways to remove all the permissions granted to the developer.
AWS CodeCommit is a managed source control service. Combined with AWS Single Sign-On (AWS SSO) and git-remote-codecommit, you can quickly and easily switch between repositories owned by different groups or even managed in separate AWS accounts. You can control those permissions with AWS Identity and Access Management (IAM) roles to allow for the automated removal of the user’s permission as part of their off-boarding procedure for the company.
This post demonstrates how to grant access to various CodeCommit repositories without access keys.
