I am trying to connect my paypal to my website and the contractor I hired to develop the site has asked me to provide him with client ID and secret key which I have to create. Is that safe to give out that information? Because once he is done building the site I don't want him to access my paypal. Or should I just change the password to a temporary password and then when he is done connecting paypal to my account I will revert to my preferred paypal password! Please advise me of a safe way.
