Account Management
WARNING: Remember your password. If you lose the password of your account, you will not be able to access that account. There is no forgot my password option here. Never forget it.
Klaytn provides two handy command-line tools, ken and JavaScript console, for developers to manage accounts. Note that exporting your private key in an unencrypted format is NOT supported.
ken
The Klaytn Endpoint Node binary ken provides account management via the account command. The command account lets you create new accounts, lists all existing accounts, imports a private key into a new account, migrates to the newest key format, and changes your password.

Data Directory
Keystore files are stored under <DATADIR>/keystore. You can specify the data directory as below. It is highly recommended to execute ken account command with --datadir option. Make the data directory point to the DATA_DIR set in the kend.conf to seamlessly share the accounts with your Endpoint Node.
1
$ ken account new --datadir <DATADIR>
2
$ ken account new --datadir "~/kend_home"
Copied!
If you do not specify the data directory, the default location is as follows.
Mac: ~/Library/KEN
Linux: ~/.ken
JavaScript Console
To connect to the JavaScript console, an EN must be in running status. For more information, see Launching an EN. Start an EN and attach to the console as follows.
Usage
1
$ kend start
2
Starting kend: OK
