 	+ Another approach is [personal access token](https://docs.gitlab.com/ee/user/profile/personal_access_tokens.html) which seems HTTPS-compatible.
 	+ Deploy/SSH key is preferred because it can be [restricted](https://docs.gitlab.com/ce/ssh/README.html#per-repository-deploy-keys) to access one repo only, unlike personal access token which has [global](https://docs.gitlab.com/ce/ssh/README.html#global-shared-deploy-keys) access.
