Passcode is somewhat different than your iCloud password.I make my passcode easy for me to remember and I have it written down somewhere just in case. Real simple people
I don't remember the answer to the questions that I made.And you can't reset your password because...?
I'm guessing the main reason you can't sign out without a password is because it would then disable "Find My" which you would not want to happen if someone stole your phone and was able to get into the phone with a passcode.
What about the recovery email address?I don't remember the answer to the questions that I made.
If your recovery email is the same as your iCloud email and you are logged into iCloud, then you do have access to the recovery email, you are already logged in.I tried email, but it says: "An email has been sent to your email address, s•••••@i•••••.com. (an email address that is apparently the same one as the email address of the icloud account that I don't know the password of, so I won't be able to log into this email address to check the email).
