# Users Tab
This tab displays all the users in the currently loaded collection, as well as their email, access level, and last sign-in date.
It will also display users who have access to your collection through a group.
{% hint style="success" %}
Only admins of a collection are able to edit and manage user data.
{% endhint %}
## Adding Users
By clicking the "Add User +" button, you can add new users to the collection. Start by setting the new user's email, and then set their user access level and an optional expiration date. Both users that have and have not yet registered for echo3D can be added to a collection.
### User Access Level
Set the access level for a user when adding them to a collection. If an expiration date has been set for a user's collection access, they will lose all collection access when the expiration date passes.
#### Admin
Admins have full access to a collection. In addition to the access allowed to [Editors](#editor), Admins are also able to make changes to the settings of the collection via the [Collections and Sharing](/web-console/manage-pages/collections-and-sharing.md) page.
#### Editor
Editors have access to all functions relating to assets within a collection. They can upload, download, edit and delete assets. They are also able to access all functionality of a collection given the subscription.
#### Commenter
Commenters can comment on assets, otherwise, their interactions are the same as that of [Viewers](#viewer).
#### Viewer
Viewers are limited to viewing assets within a collection. They are not able to upload, download, edit or delete assets.
## Managing Users
By clicking the top level menu button, you can bulk upload or download user data.
By clicking the menu button on an individual user, you can update the user's information, send them an email, or remove them from the collection.
