Hi!
I proposed in Phabricator a wile ago [0] that we adopt the term "Wikimedia developer account" across our wikis and other documentation for the LDAP-backed user accounts that are created using wikitech.wikimedia.org.
Sounds good. It's sometimes rather confusing which set of credentials is used where, and having good terminology would help that. "Wikimedia developer account" looks like a good option for this.
