There were some issues with authorization emails, but I received the email for resetting password yesterday and I could do that successfully.
I also enabled 2FA and changed my withdrawal address and received the emails for them too.
Edit:
I just tried to reset my password again and I received the authorization email in a few seconds.
Did you check the spam folder?
Really this is not good for the freebitco.in because they have built reputation in the forum and they would have resolved the issue once and foe all. The problems are getting too numerous. At first it was difficulty to withdraw and now even resetting of password though there are times the delay of email is caused by network so he has to check his network or rest and try again. hosseinimr93 thanks for helping them out.
