Creating a Dedicated Discord Account

People will often consider this secondary account a bot. Yet, it is not. 
A bot offers functions that (most of the time) can be triggered in Discord. Your dedicated second account has to be operated by a human - yourself - via a Discord client.

To limit the complexity and to not have to deal with mapping and capturing several audio devices, I chose to create a new Discord account that is solely used for running TranscriptOMatic.

Apart from using a good password, consider using 2FA to secure the account.
