As a single file editor committer I want to sign my commits so I can certify that the origin of the code is mine
**Suggested**
Modify the "Commit" button to state "Commit and Signoff"
This would append the string `Signed-off-by: {first_name} {last_name} <{commit_email}>` to the commit when submitted.

**Requirements**
We would need a designer/UX team member to look at this and come up with proposals. This is related and very similar to https://gitlab.com/gitlab-org/gitlab/-/issues/368890
