I finally got my wallet to work. I am just wondering is there a way that I can test to ensure I remember the wallet password correctly? I mean the last thing that I want to send a large number of ethereum to my wallet that I don't remember the password to.

Make sure your keyfile (named UTC--<created_at UTC ISO8601>-<address hex>) is in the default folder:

Win: %APPDATA%\Ethereum\keystore\UTC--2018-04-29T16-31-49.067329700Z--328830117705193c92fbc7aaf675f3e21d6223ca
     (i.e. c:\Users\traxium\AppData\Roaming\Ethereum\keystore\UTC--2018-04-29T16-31-49.067329700Z--328830117705193c92fbc7aaf675f3e21d6223ca)
Mac: ~/Library/Ethereum/keystore/UTC--2018-04-29T16-31-49.067329700Z--328830117705193c92fbc7aaf675f3e21d6223ca
Linux: ~/.ethereum/keystore/UTC--2018-04-29T16-31-49.067329700Z--328830117705193c92fbc7aaf675f3e21d6223ca

Install Geth (it's likely already installed together with Ethereum Wallet).


> geth account list

Account #0: {328830117705193c92fbc7aaf675f3e21d6223ca} keystore://C:\Users\traxium\AppData\Roaming\Ethereum\keystore\UTC--2018-04-29T16-31-49.067329700Z--328830117705193c92fbc7aaf675f3e21d6223ca

To list the accounts available and:

> geth account update 328830117705193c92fbc7aaf675f3e21d6223ca

Please give a new password. Do not forget this password.

To attempt to update the password to the wallet. If you Ctrl C before changing your password, you can use it to verify your password (don't be afraid of Attempt 1/3 message, you have unlimited amount of attempts, your wallet won't be blocked after 3 unsuccessful attempts, you will just have to run geth account update <address> again and have 3 more guesses).

You will probably be unable to test your password by sending a small amount of ether to another account. When sending ether in Ethereum Wallet with a wrong password it goes to very long (probably infinite) CONFIRMING... without any indication whether the guessed password was correct or not.


The most bulletproof way to test any new wallet is to send a tiny amount of ether into it and then send the ether back out again. It is an excellent idea to do this any time you are using new wallet software.
