Practice mindfulness for ten years. Train yourself to enter your deep subconscious and search your mind for the password that you forgot.

keep trying to remember the forgotten password ;) 

Unfortunately, you`'re unable to regain access to your wallet if you've lost or forgotten your password. This is because you don't have access to your wallet or your wallet password. You can read more about how our wallet works here. If you are getting the error message "Error decrypting wallet" when attempting to log in, then this means the password you're using is incorrect.

If you find yourself in this situation, I recommend trying the steps below: 

1. Try to log in using every possible password combination you may have used.

2. Your 12 word Wallet Recovery Phrase can be used if you forget your password. Enter the phrase using this form to create a new wallet that contains all the addresses and balances contained in your previous wallet. Keep in mind, this process does NOT include funds stored in any Imported Addresses.

Forget that you got a million worth of Bitcoin, LOL

You and your friend lose all of them. Nothing you can do.
That why bitcoin is very very secure.

Your friend just need to sit down and try his best to remember it. There's not a single thing that can be done about it unless he magically remembers it again. 

Bitcoin wallets are protected by 256bit encryption meaning there are 2^256 different private key combinations.

 Now, With fastest supercomputer power, it will take approx. 1.5 billion years to crack it...
--------------------------
Good News
According to Moore's law computers are getting faster exponentially every year, so if we assume that the computer speed doubles every year, then after 59 years it will take 1.13 year to crack your BTC wallet.
--------------------------
So tell your friend to wait for 59 years....
Maybe he can write it in his will for his grandchildren's so they can try cracking it...:)
