There is no "retrieved password" in the Bitcoin system. If you lose your private key, you can't get it back. Don't lose your private key.
In response to an earlier April 9 news that Bitcoin Wallet Electrum had been attacked by the botnet DoS, Devi Security Lab analysis said hackers used botnets of more than 140,000 computers to attack Electrom's nodes and simultaneously deploy malicious nodes. When a user connects to these malicious nodes and sends a transaction using an older version of Electrum, the user is prompted to update the Backdoor Client. If the user installs the client as prompted, the private key is stolen and all digital assets are lost. Millions of dollars of digital currency have been stolen, according to Electrum officials.

Wallet password: The password set for the wallet and the wallet's private key is not the same concept, the wallet password is equivalent to all the private key on your wallet for secondary encryption, if you set the wallet password, even if you get the wallet.dat file where the private key is stored, you can not view the information of the private key in the file.
The bit-pie wallet doesn't use keystore, and the imToken wallet does. Keystore is an encrypted private key that requires a password to get the private key in keystore. So in imToken, a combination of keystore and password. The stronger the password, the more secure the private key.

In the world of blockchain, the private key is the only confirmation of the ownership of encrypted assets, who controls the private key is equivalent to mastering the encrypted assets, the private key lost no one can help you get back encrypted assets.
First create a multi-sign account in the Electrum wallet, and normally a private key should be placed in a wallet. Here's a 2/3 multi-sign as an example. Suppose there are three accounts W1, W2, W3.
Electrum is a world-renowned Bitcoin light wallet with a long history of multi-signature support and a very broad user base, many of which like to use Electrum as a cold wallet or multi-sign wallet for Bitcoin or even USDT (Omni). Based on this usage scenario, Electrum is used less frequently on the user's computer. The current version of Electrum is 3.3.8, and previous versions of 3.3.4 are known to have "message defects" that allow an attacker to send an "update prompt" through a malicious ElectrumX server. This "update tip" is very confusing to the user, and if you follow the prompt to download the so-called new version of Electrum, you may be tricked. According to user feedback, because of this attack, stolen bitcoins are in the four digits or more. This captured currency theft attack is not stealing the private key (electrum's private key is generally stored with two-factor encryption), but replaces the transfer destination address when the user initiates the transfer. Here we remind users that when transferring money, special attention needs to be paid to whether the destination address has been replaced, which is a very popular method of currency theft recently. It is also recommended that users use hardware wallets such as Ledger, and if you pair it with Electrum, although the private key does not have any security issues, you should also be alert to the replacement of the destination address.
If you want to import a private key into a hardware wallet such as a ledger, you need to perform additional steps. First, you need to import the private key into a wallet such as Electrum before you can send coins to your ledger address.

Generate a random number seed, get monetics from a random number seed, generate a private key from seed and path derivation, save the private key using KeyStore, and push the private key out of the account address.
When an Electrum wallet queries a third-party Electrum server, the server can link two transactions together and know which address is a zero address.
And the private key is that when you generate your wallet, it is automatically generated by algorithm, it can not be modified, if your private key is not disclosed to others, then your private key only you know, once forgotten, you can no longer get back. As for the public key, it is calculated by algorithm according to the private key, so even if it is forgotten, it can be calculated by the private key.
