Register 2 accounts (Preferably using Gmail not third party) - Login both accounts on separate browsers - In Browser1, navigate to https://demo.weblate.org/accounts/profile/#auth - Add a new association with the Google third party link using the registered email address in Browser2 - Fill the Password and Add the Association - Disconnect the email on the account initially - Email will be changed to the new one added in (4) - Now, both browsers have the same email address i.e 2 accounts with a single email - Logging out any of the account and trying to login leads to a server error.
