i'm working on an Electron application with Metamask.
I need the private Key from the account in Metamask to use it in my application. Is there an easy way to get the private key imported into my application with an api call (with entering the password)?
Thanks
No, because that would violate entire security model of metamask.

during the node start (hard hat) I'm able to read the accounts and private keys.
I don't understand how can I retrieve it again with hard hat console
npx hardhat console
I injected even web3 library but I'm able to retrieve only the addresses.
web3:
await web3.eth.getAccounts()
ethers.js
[owner, addr1] = await ethers.getSigners()
Private keys, even of unlocked accounts, are not shared over the JSON-RPC API.
Which means, you are not able to retrieve them using web3js, ethers.js, or any other wrapper of the API.
Based on my understanding social wallet, from the point of view of a web3 app, the user's ID should not be their public key (cause that can be changed by guardians). Is this correct?
If so, a web3 app would have to have its own internal userId for each user which is mapped to their current public key. In case the public key changes (cause the guardians change the private key), then this mapping would need to change too somehow.
Is there any literature about how this change can be made from the web3 app developer's point of view?

Your understanding is incorrect. The public key / address is the id of the user.
I want to integrate Private Identity authentication into my web app, at the HTML level. How do I do that? Where do I find the iframe code and how do I get an API key?
If you want to integrate private identity into your web app, you can get the iframe code from https://github.com/openinfer/PrivateIdentity/wiki/DIV-HTML and for API key you need to go to AWS Marketplace and subscribe to Private Identity then you will get the API key Another way you can contact to support#private.id
I am trying to link an account that I created use geth with an instance of web3 that I'm running in a node repl. In order to add the account, I did the following:
1) I decrypted the JSON private key file created by Geth, in the MyEtherWallet tool.
2) Added the account with the command web3.eth.accounts.wallet.add(<private key>)
This seemed to work, but upon closer inspection, the address of the account that had been added differed from the address of the account.
Can anyone explain why this is happening, and what I need to do differently to add this specific account to web3 so that I can deploy contracts using that account?
I'm currently working on a ethereum dapp where users can login and perform transactions. I'm a newbie in dapp development. The problem is I've been trying to make something happen which is when a user registers the dapp, a wallet address will automatically be generated for that user. Any help will be appreciated
An account on Ethereum is nothing but holding a private key.
There are many software packages like web3j (for java), web3js (for javascript) which help in creating private keys and accounts.
To create a private key, you need to input a string. This string will be sent to a one-way hash function. Since private keys have to be unique for every account, the input string has to be random. Few standard practices would be using the (current time stamp + user mail id + password + random phrases) as the input string.
Once you create a private key for a user, you can generate an account for him.
Hope this helps.
