Data that is stored in the archive is encrypted whilst at rest, it is not possible for anyone to access your data if they have not accessed the archive via the application.
Occasionally, there may be instances during a support request where the support team may requests whether they can gain access to your archive account, for a limited period of time to gather further details of the experience being reported. This will help to narrow down issues experienced.
There are two options available to you.
Create a Technical Support Access Account:
You would create a Support access account/user to your archive. This support account would have the Archive Administrator role and Search Administrator roles applied. You would provide the Username and Credentials to the support representative who will confirm access to the archive, and may temporarily set a new password, if credential details were provided in a support ticket.
After the support assistance has completed, you can delete/disable the user account so the support team have no access after.
Remote Web Share Session:
Support can also be provided using remote web access services. You can provide your own remote web share service or we can assist and provide.
