Create a name for a new key (such as "CryptFolio") and click Create.
Select the info permission, and click Save. Once the key has been saved, copy and paste the Key and Secret into the "Add new Exchange" form, and click "Add account".
Is it safe to provide CryptFolio a BTC-e API key?
You need to make sure that the API key only has the info permission. This should
mean that the API key can only be used to retrieve account status, and it should not be possible
to perform trades or withdraw funds using that key.
Your BTC-e keys and secrets will never be displayed on the CryptFolio site, even if you have logged in.
Through the BTC-e interface you can revoke an API key's access at any time by clicking Disable.
