Unfortunately the ability to create alternative logins is not available at this point in time.

Is there an alternative method to achieve the same objective?

No, not that I can think of. While you can in principle host experiments on your own web space (cf. https://www.millisecond.com/products/Inquisit4/webhosting.aspx), you still need to register the respective script via the millisecond.com account (for which you need to know the login credentials, of course).FYI, here's how most institutions with web licenses under a single account and a larger web license user base handle this. Usually there are a bunch of people charged with managing the account, i.e., who are privy to the login credentials. If a researcher wants to conduct a web study using one of the institutions licenses, she contacts one of the people in charge of account management to schedule the study, writes and tests her experiment and finally submits her materials to the person in charge. Said person then takes care of making the experiment available on the web.
