OK, there is a reason why you had to register at the Secretary of State’s Election Division website and I thought it would have to be there if you registered on line. Counties do not have authority to check your name and any ID against state records, including social security, birth certificates, driver’s license, Medicare, Medicaid, etc., to see if you are a citizen and who you say you are. The Secretary of State does have that authority. They check those records against your application to determine if you are a citizen. and if any number/ID you give is actually you. You would be turned down for voter registration if the info. you gave did not match what they have or it shows you are not a citizen. Then, you also have to show a valid ID with picture when you go to vote.
You see, there is a system of checks, it’s just you did not know the system. So, feel better about voter registration and voting in your state. :o)
