You forget your email password?

There is a way to get it back by trying to log into gmail and clicking on recovery password, you can also get your password updated by using a recovery email of your gmail account.

If you are sure about the BTC private key in your email you can still recover your email, just follow the process on gmail itself.

While creating a new gmail account you will be asked to add the following so that if you lose access to the gmail account you can always recover the gmail.

1. Add phone number.
2. Recovery email address ( another email address that belongs to you )
3. You will be ask to add questions and answers yourself.

One of these three should work, if it doesn't the gmail team will ask you to wait till a special date where they will ask you the date you created the account and Aldo your date of birth, if you can pass these two you will be granted access to the gmail account again.

If you can't remember anything especially with those important details you used then your chances to recover that lost funds is close to zero.

So try to remember what email you used also the password you set since this is the only chance that you can recover your funds. But if you totally lose it then provably that this is just another case of missing Bitcoin on which the owners struggle so bad to recover their funds. I guess no one can help you in this case and also if someone sent you a message saying that they can recover your funds and ask some money to you as payment for their service then avoid it since this is just another scam.
