Tardigrade WebLogin vs Encryption Key?

Has the password which I need to login on the Tardigrade Sattelite Webpage something to do with the Encryption Key. Or can I choose. A different encryption key ?

your password for the Tardigrade account is completely separate from the encryption passphrase for your API key. However, you should be sure to back up all of these in safe places. If you lose the encryption passphrase, you will no longer be able to decrypt files you previously uploaded.
