How do you change you Profile, Console & Device ID's?

[Learning]

I pretty much have the hang of Horizon now but sometimes in certain posts ill see "make sure to change Profile, Console & Device ID's to match your own, then rehash and resign". I now how to r&r but Im not sure how to do the first part. Thanks

If you are successfully rehashing and resigning saves, you actually already know how to do the first part.

Open any of your saves in a resigner (Horizon, CONCept, etc) and you will be presented with a list of your ID's. Whenever you use a save from a secondary source, you need to change the ID's of that save with your own. As an example, if you were to download a save from here, you would need to open it in a resigner, copy & paste your own ID's in, and then rehash & resign before you were able to use it on your console.
