Hi Nicholas, note that the trading password is a different thing. The passphrase is an alphanumeric code you set when you create the api key. You have to save the api, the secret and the passphrase at the moment of creating a new api key. If you lose any of them, you need to create a new api key.
First we should understand that there is a difference between passphrase and password. When we create an API key, we get an alphanumeric code. It is important to note that we should keep our api secret and password safe. Also, you can generate a new api key if you lose the old one.
