Shared/published visualizations should be able to be used completely anonymously, so that shouldn't be a problem. (Let us know if you find otherwise.) Workflows, however, are tied to user accounts, so using them requires a login for now. Viewing workflows anonymously should be possible, however. Galaxy doesn't check the validity of user emails, so an argument could be made that all Galaxy accounts are anonymous even if they are tied to a particular user ID. Along these lines, one solution is to modify your Galaxy instance to automatically create anonymous users as needed. When a user wants to use your workflows/visualizations, then they're directed to create and use an anonymous account; the instance could then periodically (e.g. 1 hour/day) delete all anonymous accounts. Please do share your solution with the list when you come up with something workable. Best, J. On Jan 14, 2013, at 11:13 AM, Sveinung Gundersen wrote:

Hello all,

We are wondering if it is possible to activate anonymous use of the workflows and the visualization (trackster) features of Galaxy, somehow?

This is a strict requirement for the acceptance of our new paper in a specific journal.

Hack solutions are also welcome!

Thanks, Sveinung
