local node account unlocking and passwords

When using a local node, such as Geth or Parity, the account in the keychain has to be unlocked with a password before any transactions are successful.

That can be accomplished in one of two ways:

• when deploying, sending or starting, using the -p or --password option, along with the password to unlock the account. it will not be saved anywhere.

• in your shell environment, the password for the account you are using can be set in the environment with EZO_PASSWORD. Ezo will use this password to unlock the account without the need to specify a password on the command line. However, if a password is present on the command line, it will take precedence over the environment setting.
