# Access Control

ngSurvey can be used by multiple [users](https://docs.ngsurvey.com/multi-user-management/users) at the same time and any number of users can connect simultaneously to the administration interface. You may grant specific [access rights](https://docs.ngsurvey.com/multi-user-management/roles) to each [user](https://docs.ngsurvey.com/multi-user-management/users) or [group](https://docs.ngsurvey.com/multi-user-management/groups) to give them more or less control over the administration interface and the features they can use.   

{% hint style="info" %}
User project items like forms, custom answer types, styles or panels are isolated from the other [users](https://docs.ngsurvey.com/multi-user-management/users). Only administrator are allowed to see them all without any restrictions. You can of course change [access rights](https://docs.ngsurvey.com/walkthroughs/share-a-survey) to surveys at any time and [grant additional users](https://docs.ngsurvey.com/walkthroughs/share-a-survey) or groups access to the same survey or folders.
