SPD workflow impersonation step, who counts as author?

Question

Impersonation Step quotes "The contents of this step will run as the workflow author"

Will impersonation steps run with the credentials of the person who publishes a workflow the last time?

If an author goes obsolete, hence their credentials become invalid, do all workflows need to be re-published by someone with appropriate permission level?

Answer 1

Yes the Impersonation Step(s) will run as the last person who published the workflow, so you might have to republish them it the permissions of that person changes.

Or if possible create a User Account which is only used to publish workflows.
