We are using confluence wikis for our end-user software documentation. Due to the industry we work in, we cannot make this documentation available to the general population, ie our competitors. We offer dozens of software tools and each has its own extremly large wiki. It is neither practical to create one login for all clients to view all documentation, nor is it practical to create create a separate licensed account for every single one of our clients.
I have not been able to find a plugin or native feature that would allow me to accomplish this and, honestly, I'm pretty flabergasted that Atlassian doesn't off read-only logins that don't use a license. All of the tools we use offer this other than Atlassian.
