# User Permissions
Different users in Auctria can have different permission levels set.
These levels are summarized in the table below.
|None||No permission to view or edit the auction. This is typically used to provide per-auction permissions: you can set a user's default permission to None and then assign permissions in specific auctions; or, use None on a per-auction basis to deny access to a specific auction|
|Read Only||The user can view the auction data, but not modify anything.|
|User||Permission to make normal changes, such as: add bidders; add items and donors; record bids; and, process checkout payments. However, the user is not able to delete anything. Also, some bulk operations (e.g.: sending statements to all bidders) are also blocked.|
|Power User||The level is the same as a user but with permission to delete records and perform all bulk operations on an auction. This level cannot perform organization level operations such as creating a new auction and adding/deleting users.|
|Admin||All powerful! Can manage the organization, as well as users. Required to set-up Text Messaging. Only admins can issue credit card refunds.|
Users will have a default permission listed on the Users pages for the organization.
# Auction Specific Permissions
You can also assign a user a specific permission in a particular event. For example, a user may have Read Only permission by default, but is given User permission in an event they are helping with.
Auction level permissions are defined on the Auction Details page, see Auction Permissions
The "Unset" permission level literally means the permission level has not been set.
A User that has been assigned this permission level will have "PowerUser" access.
