Why use an API key and secret?

December 23, 2022 by Tarik

You need two separate keys, one that tells them who you are, and the other one that proves you are who you say you are. The “key” is your user ID, and the “secret” is your password. They just use the “key” and “secret” terms because that’s how they’ve implemented it.
