# Give access to DCSR NAS files to an external collaborator There are two administrative steps: 1. The external collaborator must ask a UNIL account using [this online form](https://www.unil.ch/ci/id) (go to "Obtenir un compte informatique personnel"). Warning: in the online form, the external collaborator have to write the name/email of the PI who is sponsoring the UNIL account in the comments section. 2. the PI (Principal Investigator) to whom the external collaborator is related must use [this application](https://conference.unil.ch/research-resource-requests/) to add the collaborator into the appropriate project. Log into the application if necessary on the top right, and click on the "Manage members list / GĂ©rer la liste de membres" icon for your project. The usernames always have 8 characters (e.g. Greta Thunberg username would be: gthunber) The external collaborator can then access the data of the project stored on the UNIL NAS using VPN: - [Install and use the UNIL VPN](https://www.unil.ch/ci/fr/home/menuinst/catalogue-de-services/reseau-et-telephonie/acces-hors-campus-vpn/documentation.html) - [Access the NAS from a laptop](https://wiki.unil.ch/ci/books/research-data-storage/page/data-management)
