Why do I Get Warning “A data breach on a site or app exposed your password” in Chrome?

When trying to register or adding agent on Omnichannel with Chrome browser, you might get a pop warning you about possible data breach that contains your email and password.

This pop up message says, "A data breach on a site or app exposed your password. Chrome recommends changing your password on omnichannel.qiscus.com now.“

When you type your credentials into a website, Chrome will now warn you if your username and password have been compromised in a data breach on some site or app. It will suggest that you change them everywhere they were used.

it does not matter on which website you see this new notification. The new message is a notification about the username / email and password combination that you just entered. That combination has been compromised in a breach of a website or app.

Change your password on all websites or apps where you are using the same username / email and password combination. Make sure in every apps and web you use different password.

As of now, Google Chrome doesn’t show what site and app causes the breach, because they use heavily encrypted and secured algorithm. So the best action would be to change the password for your email.
