# Access Control

ngSurvey can be used by multiple [users](/multi-user-management/users.md) at the same time and any number of users can connect simultaneously to the administration interface. You may grant specific [access rights](/multi-user-management/roles.md) to each [user](/multi-user-management/users.md) or [group](/multi-user-management/groups.md) 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](/multi-user-management/users.md). Only administrator are allowed to see them all without any restrictions. You can of course change [access rights](/walkthroughs/share-a-survey.md) to surveys at any time and [grant additional users](/walkthroughs/share-a-survey.md) or groups access to the same survey or folders.
{% endhint %}
