Lost password for elecrum

[naqaa]

Hello, I have lost my password for Electrum. The wallet is password-protected, and I cannot access it, but I still have the original file.
The password I had was either 8 or 9 characters long, and it is lost.
I created this password from a 15-character one which I still have.
What options do I have for recovery?

My ssd with all password and seed phrase-dead (samsung evo 840- cant reboot this, The disk firmware or decryptor has been corrupted, and there is no way to decrypt it.)

im used translator, sry for bad eng.

If it is the wallet password and you have the seed phrase you can actually import it into a new wallet and it will recover the wallet. Only the passphrase will stop you from recovering the wallet

For password recovery you can make use of https://github.com/gurnec/btcrecover but the problem is you might need to remember some characters in the password or anything.

Here is the guide on that recovery https://github.com/3rdIteration/btcrecover/

What is this 15-character one means?
There is a wallet recovery service [I can not remember their name, hopefully someone will give the link], try them.

It's always best practice that you write down your seed words with any password you have so that you can restore the wallet easily. You actually don't need the password if you had the seed known to you.

I only have a long password from which my payment password was derived, and wallet files.

If you have the seed phrase, you do not need the password. Only what you need is to import the seed phrase into Electrum again and set another password.

If you do not have the seed phrase, use btcrecover if you remember part of the passwords because the longer the password characters are the harder it would be to recover.

I assume you created a password containing 8 characters from your 15-character list and you have an electrum wallet file too.

So brute-forcing the password is definitely possible and with the wallet file, you just can install Electrum on any PC and try to open the wallet file by trying the possible combinations.

Another thing you can do if you can't decrypt the wallet file is try data recover your SSD which is definitely possible but highly expensive.

I think the important question here is how did you derive your password from a 15-character one? Do you remember the process or did you use some tools?

My ssd with all password and seed phrase-dead ...

Based on this, I assume that you don't have a seed phrase written offline on a piece of paper or a similar medium. You know that's bad practice, right?

What is this 15-character one means?

I assume that the OP created his Electrum password by choosing 8 or 9 characters from a string of 15 characters, which can greatly help him recover the password, whether he tries to do it himself or with the help of professionals.

There is a wallet recovery service [I can not remember their name, hopefully someone will give the link], try them.

The only service of this type that has a very good reputation is this one -> Bitcoin Wallet Recovery Services - for forgotten wallet password

This is the one I had in mind. Thanks for the link. OP can try it.

I think you can still able to revive your SSD if it is just corrupted or undetectable you can try the power cycle method because SSD has a self-repair feature to fix corrupted and undetectable issue. Check the guide here
I have experience with my Samsung SSD before it was undetectable on Windows even on the BIOS I just repaired the SSD through the power cycle method.
So try this it might be also work in your SSD if it does not work try to resolder the SSD terminals.

If it still does not work you don't have any other choice but to use the service provided above or brute-force the wallet file using the BTCrecovery tool.

I took it to a specialized recovery company, and they told me that if the encryption controller is damaged in Samsung 840 and newer versions, it cannot be recovered. Only the factory can do it.

Have mining rig, may be btc recovery for new ssd and file electrum, and bruting?)

I only have a long password from which my payment password was derived,

Have you used any special or unique methods to derive your 8~9character password from the 15characters?
If yes, then it wont be possible without knowing the exact method that you've used.

Or have you picked random 8 or 9 characters from those 15 without using duplicate?
If yes, bruteforcing an 8~9 character password with BTCRecover from 15 characters is quite doable with roughly, ¹⁵P₈ plus ¹⁵P₉ maximum number of combinations.
But you need a fast processor for this since it may take months with old generation processors, plus it wont work with GPU.

For the setup, read through the updated version's official documentation: https://btcrecover.readthedocs.io/en/latest/INSTALL/
Then, the usage: https://btcrecover.readthedocs.io/en/latest/TUTORIAL/
(DYOR since it has all the info you need)

And here's a short guide for your case:

• Your "tokens.txt" should compose of your 15 character long password, one character per line.
• You would need to add --length-min 8 --length-max 9 to specify that your password can only be 8~9characters long.
• Due to the billions of possible number of combination, you may have to add --no-eta -d to skip the initial password counting procedure.

Here's an example command:

Code:

python btcrecover.py --wallet default_wallet --tokenlist tokens.txt --length-min 8 --length-max 9 --no-eta -d

what processor need for this?

If you did not generate these 15 letters randomly, then the probability of knowing the correct password is high, but you need to reduce the search results a little. Do you remember any letter or any order of letters or anything that reduces the number of letters to 5 or 4 or at least excludes a specific order?

what processor need for this?

Use the best one that you have, for reference, my quite old i7 4790 can only do 3.9k P/s (Passwords per second)
With that, it could take a week to go through all the possible combinations.
Besides, the correct password may be found near the start, mid or last part of the search, so the actual time still depends on luck.

To test your best processor's capability, you can test it with the command:

Code:

python btcrecover.py --performance --wallet default_wallet

Make sure that the selected wallet is your actual wallet file or has the same version.

Then make a rough estimate on how long it would take to exhaust all of the possible combinations with that rate.
Take the maximum number of combinations that you can search: ¹⁵P₈ plus ¹⁵P₉ is equal to 2,075,673,600 combinations.
Let's say that your processor can do 10kP/s which is equal to 10,000 passwords per second, it will take: 2,075,673,600 / 10,000 = 207,567 seconds (58hours) to exhaust all those combinations.
If you're lucky, you might found it at the first hour or if you're not, right after 57 hours.

Depending on how complicated your passwords usually are and how many GPUs you have access to, you might be able to brute force it using hashcat or johntheripper, I think btcrecover might be able to crack electrum wallet passwords as well. I also see someone supposedly wrote a python script over GitHub called pwscanx.

None of these are going to have a simple guide, it's going to rely on you doing the work to get familiar with the tools, or paying someone who already has the knowledge to do it for you. Even then if you used a sufficiently complex password, it may be impossible.

[BitMaxz]

what processor need for this?

It would be much better if you have a GPU it is way faster than just a CPU.
If you have a mining rig with multiple GPUs (You mentioned above)you can temporarily use it to crack your password much faster than running it with a single CPU.

Read this for GPU acceleration https://btcrecover.readthedocs.io/en/latest/GPU_Acceleration/

[nc50lc]

It would be much better if you have a GPU it is way faster than just a CPU.

Take note that when bruteforcing Electrum wallet passwords, it'll be limited to --enable-opencl instead of --enable-gpu.
The latter wont work on it and the former is still experimental which will only work in select GPUs.

He also have to use the forked BTCRecover by 3rdIteration that is not older than v1.2.0.
