Hi Moushira,
You and others can access superset by meeting the items on this list https://phabricator.wikimedia.org/project/profile/1564/
Also, in case it's helpful, here are some steps you can take:
# making sure that you have a signed NDA on file. Reach out to legal if you don't or if you aren't sure so that they can confirm
# setting up an LDAP (aka Wikitech aka Wikimedia Developer) account. Go to https://wikitech.wikimedia.org/wiki/Main_Page and click on create an account on the top right 'create account' link. You will need to know your shell user name. See below for a little more about this.
# Once the account is set up, you can request access. Here's a sample access ticket T243103 request (the access here includes access to superset). Create your ticket using [[ https://phabricator.wikimedia.org/maniphest/task/edit/form/1/?projects=ldap-access-requests | this ticket as a baseline ]].
# See [[ https://phabricator.wikimedia.org/project/profile/1564/ | this page ]] for all required info.
# Lastly, FYI, There's a training coming up on Jan 22, 2020, carried out by product analytics, which will be recorded. I can share that recording link when it is available.
If you don't know your shell user name, take the following steps:
a) If on a mac, use Finder to open Terminal
b) type
`echo "$USER"`
OR
`whoami`
c) copy the shell user name that is returned and include that in the UNIX shell user name field
