Before creating this topic, I searched for my question here and on google and no success.
Only this topic is relevant, but although it’s closed, I couldn’t find the answer in the link suggested by @jerdog
Anyway, I’d like to specify my question. I want to test our application and how it behaves for a user, whose password was leaked.
By the way, the following text from here seems to be outdated (or maybe I don’t get it clearly):
You can customize blocked account emails. To test, enter the email address email@example.com and password Paaf213XXYYZZ, and select a connection type. Click Try.
I don’t know where should I enter the password. And as I wrote, it helps (without the password) to test the configured template, not the integration of breached password detection with our app.
