■□□□□ Interesting thread!
“I used few patterns to get login access to 1500+ facebook accounts
With few accounts, I have done as below which confused account holders
Even this is not been approved for bug bounty
I did this in 2011
Maybe fb want to increase number of registered users.
So here is what I did.
Assume that FB account has OLD eMail, OLD Pass
I created NEW eMail and changed eMail of FB account to NEW eMail
I also changed Password from OLD Pass to NEW Pass
Now OLD eMail based FB account shifted to NEW eMail & NEW Pass
A fresh account is visible by using OLD eMail & OLD Pass
So, FB account holder can still login but they find it as fresh account as everything already got moved to new account.”
