1) I believe you are talking about the “Personal Access Code” you need to enter when AnonAddy asks for it when installing the “AnonAddy extension” to your browser. But this process takes place AFTER you have signed up for AnonAddy.
2) It is important though to use a REAL email address when you initially register for AnonAddy. There is a field where you are asked to fill out the “Human Verification Code”, and you just type what you see on your screen in that field. These can be tricky. Pay attention to CAPS, don’t confuse letters like q for the number 9, etc. Type EXACTLY what you see. Then make sure to check the box “I accept the terms and privacy policy” before you hit the “Register” button. After that AnonAddy will send you 2 emails, one to verify your email address and one to confirm your payment.
I hope this helps.
