Please don't laugh at me as I think I know the answer but I want to double check before I am locked out forever. 
My self assessment password is automatically saved on my computer and I have just completed the form but it is asking me to verify the password before it can be submitted. I have no idea what this password is.
I have my user ID but when I clicked on forgotten password it states that I need to know my government online email address to receive a new password by email. Is this my usual email address? HMRC have emailed me a reminder so I must have provided it in the past. It also states my current password will become invalid immediately so I am wary to jump in and ask for a reset.
It also states I need details for each service I am enrolled for, I think it is just self assessment but not sure about National Insurance.
