The Anonymous user is a system account that does not require authentication using credentials. It is disabled in Appian, by default.

The Anonymous account:

• Must be enabled if you need to send email messages to start process models.
• Is denied access to all other objects, pages, applications, or items in the portal other than the right to trigger a process using email.
• Is automatically in the Application User Role without you needing to add it to the role's group. Adding the anonymous user to another user role has no effect; it will always be considered in the Application User Role.

Enabling Anonymous Access

Enable the anonymous account by creating the following setting in custom.properties.

1
conf.suite.ANONYMOUS_ACCESS=true

After making any changes to this property restart both the application server and the Appian services.
