Kusiak in Welcome to the forums!

Hi, this is a temporary account, but I need to know how to retrieve my original account back on a different device.

You need to log back with the same authentication method you used for your main account (or one linked to it). Note that you need to use the same account that has been link to notify otherwise it will log you in a new account. If you have problem accessing it, Akyoto may be able to help you on the discord server
