How to connect different Atlassian Jira accounts

[Carsten Nielsen]

We have several IT vendors, who use Jira (naturally their own account).

As we receive accounts for their Jira versions, is it possible to combine these into one account and view internally (we are using the same work email address as account name)?

So e.g. Vendor 1 gives us access to Jira through their account, and Vendor 2 gives us access to Jira through their account.

If we create a company Jira account using the same email address, will we be able to integrate vendors Jira accounts and thus multiple projects, so we don't have to log on to several different Jira instances?

You may want to look at an addon to help with this. While I haven’t personally used it, I’ve seen this one around and it seems like it might help
