when you have forgotten the password of the bitcoin wallet that you have then the only way you can only change the password is by using the registered email by the method of forgetting the password and contacting support, and if you don't have access to your email then surely you don't can return the wallet you have.
You probably did not read above by the OP. He falls on a trap and using a phishing wallet. We all know that Online wallet is prone to hacking and scamming. That's really bad news for OP. Well, if ever you had been lost your password try to use the link sent in your email including the code but if you also forgot your email then that's very hard to recover. Maybe you can contact the customer support and ask for help on what are the documents you need to provide in order to recover your bitcoin wallet. I hate online wallet, OP has a good decision to switching into hardware wallet and be careful by next time.
Use an electrum wallet just for free and install it in your clean Pc. By the way OP better to lock your thread if you have been got successful answer.
