dcrlncli changepassword - Change an encrypted wallet’s password at startup.
The changepassword command is used to change dcrlnd’s encrypted wallet’s password. It will automatically unlock the daemon if the password change is successful.
If one did not specify a password for their wallet (running dcrlnd with
--noseedbackup), one must restart their daemon without
--noseedbackup and use this command. The “current password” field
should be left empty.
