So i was trying to sign into one of my apps on my phone, and i kept inputting a pin wrong. Eventually i cancelled, and when i did, i got a notification on my iphone telling me that all of my accounts that had reused passwords were in a data leak. I dont know if this was because of the pin issue or if they actually were compromised.

Any insight would be great, because last time this happened was when i was recovering from a computer virus and thought it was still in my hard drive, but now i think it might have just been the pin problem. I reset all my passwords anyway just in case.
