# Create user account The Create user account action node creates a new [user](https://docs.appfarm.io/reference/security/users) in the solution or can optionally update an existing user. [Roles](https://docs.appfarm.io/reference/security/roles) can be assigned to determine the user's permissions. A welcome email can be automatically triggered, enabling the user to login immediately. ## Usage This action node is used when you would like client users to be able to give other people access to the apps in a solution. For example, a client user with a custom *Administrator* role may be granted the permission to add users with a *Coordinator* role. Users in a solution must have unique email addresses. The default behavior of Create user account is to throw an error (UserAccountAlreadyExistException: Appfarm error code 14007) when run with an email that is already assigned to user in the solution. To allow existing users, and optionally update their User object, select the **Accept Existing User** checkbox. When the action node successfully completes, the User object is immediately created in the database. It is not necessary to persist any changes. {% hint style="warning" %} **Important** * The user running this action node must have a role with the appropriate permissions to create a new user and assign any selected role. Read more under [Users](https://docs.appfarm.io/reference/security/users#permissions). * The appropriate user account manipulation properties must be enabled for the relevant [environment](https://docs.appfarm.io/reference/configuration/environments#user-account-manipulation). {% endhint %} ## Properties
