type ChangePasswordArgs struct {
	OldPassword string `json:"oldPassword"` // Current authorization password
	NewPassword string `json:"newPassword"` // New authorization password
}

ChangePasswordArgs ...

type NewTokenArgs

type NewTokenArgs struct {
	Password
	// Endpoints that may be accessed with this token
	// e.g. if endpoints is ["/ext/bc/X", "/ext/admin"] then the token holder
	// can hit the X-Chain API and the admin API
	// If [Endpoints] contains an element "*" then the token
	// allows access to all API endpoints
