Retrive password without email?

Hello,

I know someone who has an old account and would like to log in to it, but they forgot their password, and the email they used to make the account. If this person could fid out which email was used to make the account, then they could reset the pass. Is there a way to find this out? or another way to change password Thank you very much.

No.
I mean technically it is possible, but this information is personal and won't be shared with anyone.
There would simply not be any guarantee that the person who is asking is indeed be the actual account holder.
So, if you care about your account, don't use throw-away email addresses.

@bufferunderrun dangit. The username was REALLY catchy and unique.

Well, they would have to go through all the email addresses that they use then. No other way, I'm afraid.
