If you enable public signup for your FishEye system, visitors can create their own FishEye user accounts via the 'Signup' link on the login screen:

Public signup is disabled by default.
To enable public signup,
- Go to the FishEye 'Admin Menu'.
- Click the 'Users/Security' link in the left navigation column.
- The 'Authentication Settings' page will be displayed (see screenshot below).
- Next to 'Public Signup', click the 'On' link.
- Log out of FishEye and verify that the login screen now contains a 'Signup' link.
