That's an unusual scenario, to say the least. So

https://mysite.com/item

is your baseUrl and you need to visit

https://sekondsite.com/

for additional authentication. I would have expected a test flow like this: * Login

https://mysite.com/item

(as your code is above) * Validate that the page has fully loaded using

cy.request()

* Validate the state of the images that are waiting to load (the process will depend on your app) *

cy.origin()

into

https://sekondsite.com/

and authenticate * Come back to

https://mysite.com/item

* Validate that the images have now loaded (the process will depends on your app)
