Topic: If I forget wallet's password? - page 3. (Read 770 times)

Lol, tell that to the people who recovered what is now millions of dollars in Bitcoin by using professionals to decrypt their wallet! Somehow I doubt you'd have the same idea if you had a wallet.dat sitting there encrypted with 10 BTC or something. :p

It is said that the services of different shamans and psychics are becoming popular in the United States to restore lost passwords. The truth about the effectiveness of this method has not yet heard.

My thoughts exactly but then again if that money is already lost for you what else can you lose, right? It's a gamble but if it's your last chance to get your coins back then it's OK to go for it.

Another way around this is if he has the recovery password though because  I remember there was a time I needed to install Electrum during the creation of account section, the question was asked if I have a seed and I had to which brought out the wallet then one can continue from there. But what I am not sure is if the password was still required after I entered the seed I have. The point is, one just need to be very careful and do the necessary backups in addition to having a unique password that can easily be remembered no matter the situation because you never can tell when your memory would fail you that you have to fall back to default mode which at that point would  be a life saver.

You can still get back your coins if you have the private key and import it into a new wallet or had backed up your wallet before the password was created and import the back up file into a new wallet.However, If you don't have either of them, i am afraid that your coins will be locked forever.

If I forget wallet's password?
First of all you can try to remember your password.you can also use the 12-word wallet recovery phrase.Another way is you can try a password cracker tool as a last resort.Before start the process you need the latest version of your bitcoin wallet file.

A very big shock you will receive as you forget your wallet password.at first you would look stupid and foolish.Fever will immediately show up and by your self,you start reacting your body that's if you have a high amount of BTC stored in your wallet.

Wow.I Never heard of that kind a service before.Thanks for the information.

one thing you should always remember is that having a wallet is like holding a crucial nuclear codes. Always keep in mind to have a copy of your recovery codes and passwords both digitally and handwritten on a paper. Value wallets as they are you wealth.

And sad to say, it can be recovered, but if you are only willing to pay hackers for your account. And if u haven't, im sorry to say bro.

Yet, try your best to recover it, try every passwords u can think of.

Well, it is desirable to save the file wallet.dat-it's your habit to enter-immediately save the file separately to the USB flash drive.
Try to return to the recovery point-in some cases it helps.

Yes, depending on how much and how accurate the clues you can give them are to break the password it can take a very long time for sure.

With the other point it's then important to choose a service that has a reputation. I know there's at least one guy who's been doing this for years and makes his money by taking a cut of the found Bitcoin. He has a reputation to protect, so it's a bit unlikely that he'd throw it all away for one score when he can continue making a steady income for years.

How much time is "tons of time"?

If your password always has 1979 AND a capital letter, (assuming that the rest of your password uses only the letter, numbers, and symbols found on a standard U.S. QWERTY keyboard)

Then it would seem that (if I've got my maths correct) there are:

96*26*95*95*95*95 = 203,300,760,000 possible passwords.

If the service can try 100,000 passwords per second, then they could crack it in less than 2,033,007,6 seconds.  That's less than 24 days.

If they can try 1 millions passwords per second, then it will take them less than 2.5 days.


It requires a bit more technical ability on your part, but it is possible to provide a service with ONLY enough of your wallet for them to know when they've found the correct password without providing them enough information to access your private keys.  In this way, if they lie and say that they couldn't crack it, then they won't ever get anything.


Well, in that case, you've already lost the coins anyhow.  So, you haven't risked anything by trying to get the password cracked.  Sure, they've taken something that they SHOULD HAVE returned to you, but your alternative is: "not trying to find a trustworthy service", in which case you are no better off than having tried and found an untrustworthy service that took the coins.

There are tools out there for brute-forcing wallet passwords. I'd recommend trying only the open-source ones.

That's what i thought when i first heard about these services, if they able to crack the password through your provided hints then they will have full access to your wallet and you never know what they are going to do with your BTC, you can't claim your BTC from them.
But as you have no other option, this would be the only thing you can do and expect positive response from them.

It would still take tons of time. Also you are trusting the provides of said service to not screw you up once/if they are able to bruteforce the missing characters of the password. I know I wouldn't trust them, they could claim they weren't able to uncrack it, get your coins, and then a couple of years from now they may move it when least expected (and when BTC will be worth $100k+

I have lost HDDs because I screwed up while entering the passwords and they are fully encrypted, I just assume I cannot access these disks anymore, it's not worth the effort. If OP doesn't have much BTC then forget it and start getting ready to buy the dip, and this time remember the password.

Like someone else mentioned earlier, there are actually services that can be successful in cracking peoples password.

Basically they have a decent chance of succeeding the more information you can give them.

If you can tell them that your password is 9 characters long and always has 1979 in it and one capital letter, they can use that as a start to set some settings for brute forcing it.

Only if you have the code to restore your wallet. Otherwise it is impossible. It shows the high security of the currency.

Except if you have backed up your private keys separately with the command 'dumpprivkey' or 'dumpwallet'. It is possible to import your private key in another wallet.

A private key looks like this.

If you are talking about Bitcoin Core, then yes. You will either need the unencrypted wallet file or the password to decrypt it and spend the coins.

If you have a high amount of BTC stored in your wallet, you could try a service that brute forces your password, like Wallet Recovery Services for 20% of your wallet balance.

I forget coin's window wallet program's password.

So I can't send coin.

Then this coin is lost forever?

Are there no restore method?

Just default qt wallet program.
