Imagine a Bitcoin with millions of dollars but could not access it. More and more people cannot use digital wallets because they forget the password. This is reality. toll? It is estimated that $ 140 million is hidden in the locked wallet. And because cryptocurrencies are decentralized currencies, when you forget the wallet access password, you can't find someone who can provide help. So what can be done?

What does it mean? Have you forgotten the password? Don't know the help of the word?

It is a safe approach to get the key and backup it to a safe place, which allows you to access your wallet. If you do not do this or remember the notes, I will be incomparable. If it is multiple signature wallets, 2/3 signatures are required. I need more information to help.

However, if Blockchain supports that it cannot help you restore your password, what other choices do you have? First of all, if you forget the password but remember to use the email address used when creating a wallet, you can ask them to send you all wallet created using the address.

The link of the service and all the upcoming services and software tools you need to download are in the guide. If you don't remember emails, there are several other options to restore encrypted wallets.

You can use the open source Bitcoin password and seed recovery tool BTC Recover to download the encryption backup. To this end, you need to install some Python libraries and familiarize the command prompt because it does not have a graphical user interface.

If you have Wallet.aes.json backup and do not remember the wallet ID, you can guide the wallet into the new Blockchain wallet. Finally, if you create a second password on your wallet, you will be able to use the password to crack the password.

To this end, you need to be equipped with a GPU device for one or more NVIDIA or AMD video cards, which can try thousands of different passwords per second. In addition to having a GPU card, you also need to use software tools such as Hashcat to run a password to crack you.

If you still can't find any passwords, you can use a bunch of different word lists to store the repository. Make sure you have enough memory space and bandwidth, because many of these words list are between 10 and 30GB.

As you can see, you need some programming skills and related hardware to try to restore your wallet. Remember, if all this seems to be important for you, professional services with charges can help you find the lost Blockchain wallet.

Break the code

Because the technology of the blockchain is so strictly protected, it is common to forget the password.

"People think they will remember what they create," he said. "Then, 10 years later, they did not."

Carmitchel said that a password requires $ 500 computing power every day, and added that DataReCovery uses various hackers to find the lost key. If the customer has forgotten the password many times, the cost of recovery process may be high.

The password can be created by the owner or the computer can be generated. Camichel said that it is not surprising that there is greater opportunities to solve the varieties of humans. He will start the process by asking the customer as much information as possible to find the model: for example, customers may tend to use capital letters or specific symbols when creating a password. "This looks simple ... but it eliminates millions of combinations," he said. Carmitchel spent a week to crack a key created with the left speak. One of the symbols was used to replace a letter. Finally Find a given dictionary.

If the password is generated by a computer, such as the BIP 39 generated by the aid, it will automatically create a password of a 22 words. Camichel said that the chance of combining these words in the correct order is "astronomical number". He said DataReCovery cracked about 80%of the request. But this left 20%of the password is irreversible. Even if the violent attack is used, this method depends on the possible combination of speculating the target password until the correct password is found. This is the most aggressive hacker attack form.

Rely on third -party suppliers

CPA Jennifer Fiddian-Green said that blockchain technology is so new that we are still trying to understand it that he leads the company's national evidence collection and dispute solution consultation and anti-money laundering service practice. "The real advantage of blockchain technology is that it is very safe," she said. "You can't just say, 'I will call the bank to prove who I am, and then get my money.'"

Fiddian-Green said that because of this security and risk level, people are turning to third-party providers (such as cryptocurrency exchanges) to store wallets online for them. However, these third parties have just emerged, and emerging industries have not provided the same type of protection as the traditional banking industry. In 2020, at least 75 cryptocurrency exchanges were closed, and people could not access their cryptocurrencies.

"We will not easily cause this situation to happen in the banking industry. We have a lot of protection and supervision," Fiddian-Green said. He cooperates with these exchanges in Canada and International to protect and establish a system to ensure transparency and better. Protect their customers.

Security vulnerabilities are another potential issue, CPA Canada is responsible for research, guiding and supporting CPA Michael Wong supplements. "Through these third -party exchanges, customers entrust the private key of Bitcoin Wallet to them," he said. "Malicious actors can use vulnerabilities in the computer system to destroy the firewalls and other security measures, so as to illegally access the customer Bitcoin held by the exchange."

Although they provide a convenient way to trade cryptocurrencies, the method of Wong safely stores Bitcoin is to make your digital wallet's private key offline. One of the safest ways is to use hardware wallets. Other offline options include stored your private key on a USB that is connected to the Internet or write it on a piece of paper.

"Use these methods to visit your Bitcoin's only way is to physical access to the private key," he said.

Step of the method of unlock your blockchain key:

To transfer intelligent envelopes and files, release goods, or manage other blockchain keys (these are blockchain operations), you need to unlock your blockchain key first. After unlocking the blockchain key, you can use it for digital signature and start the blockchain operation.

prerequisites:

You must have an effective blockchain key link to your account.

Your account must have appropriate permissions to be allowed to transmit envelopes and management documents: "transmission documents and creation envelopes", also known as "document manager".

Step 1: Check the status of your blockchain key

In the upper right corner of the screen (your avatar, expressed by your photo), you will immediately see whether your blockchain key has been unlocked and prepared to sign the blockchain operation (green key icon) or is still locked (Red key icon).

The green icon indicates that your blockchain key has been unlocked and prepared to sign a digital signature of the operation you will execute.

If the key icon is red, click your avatar image to open the pop -up window, and then click to unlock your blockchain key button.

Step 2: Unlock your blockchain key

The public address of the blockchain key to your account will be displayed together with key type information and links to your account.

You will see a description of how to unlock the blockchain key. These will depend on the type of your blockchain key.

To continue, click the gray selection file button and select the downloaded blockchain key file from your computer. Then provide a encryption password for your blockchain key in the following field.

Click the green unlock the blockchain key button to unlock your blockchain key. The key is now unlocked in your network browser.

Step 3: Re -check the status of your blockchain key

After a few seconds, the window should disappear. The state of your blockchain key should become unlocked, and the green key icon is also represented by the green key icon in the upper right corner.

Congratulations, you have unlocked your blockchain key! You are now ready to sign a digital signature on a blockchain -based transaction on the Cargox platform.

Future security

The good news is that with the advancement of technology, we may have the ability to restore these forgotten passwords by cracking and encryption, Wong said.

"With quantum computing, the computing power is exponentially increased," he said when he talked about this expected technology. "Although the current computer may take millions of years to solve today's encryption, quantum computers may be completed within a day." Wong said that the exact scale may be different, but experts agree In any existing classic computer. "This will change the paradigm of cryptographic overall," he said. "This will affect the blockchain and anything that uses encryption." Our data (including Bitcoin) is not affected by quantum computers.

Whether you choose to manage your password, print and save it in a safe through the password manager, or protect it through a third party, he reminds users to take responsibility. "Treat it like any other financial asset password and use it carefully," Wong said. "Don't keep it around ... but make sure you can always access it."

The above introduces how to unlock cryptocurrencies when you forget the crypto wallet password. Your password will not be shared by the blockchain, and your password cannot be reset or access. The main way to restore wallet is backup phrases. Make sure you write down your backup phrase, which is the only way to restore wallet access permissions when the password is lost.
