Is it required to use the Intuit eSignature process? Can I efile a return without using this process? If I mark the 8879 with the taxpayer authorizing me to enter their PIN and use the autofill option for that is it OK to proceed with efiling without sending the 8879 to the client with the eSignature process?

The FAQ I reviewed implies it is not required to use Intuit's eSignature process, I just want to confirm that with my fellow experts, who are obviously more expert than I am.
