ethereum account update <address>
Update an existing account.
The account is saved in the newest version in encrypted format, you are prompted
for a passphrase to unlock the account and another to save the updated file.
This same command can therefore be used to migrate an account of a deprecated
format to the newest format or change the password for an account.
For non-interactive use the passphrase can be specified with the --password flag:
ethereum --password <passwordfile> account new
Since only one password can be given, only format update can be performed,
changing your password is only possible interactively.
Note that account update has the a side effect that the order of your accounts
