Hello,
I see you want to disable two-factor authentication. For some background I suggest you read the document: "Two-factor authentication for Apple ID" - Two-factor authentication for Apple ID - Apple Support
When reading that article some people have difficulty determining if they can or cannot disable two factor authentication on their accounts, particularly when provided with isolated quotations. I am providing what I feel is clearer information.
Several years ago Apple transitioned to using two-factor authentication for additional account security. Accounts created since that time automatically use two-factor authentication and this cannot be disabled.
Some people have older accounts from before two-factor authentication was mandatory on new accounts. Apple encourages those users to transition to two-factor authentication when signing in on their accounts because without it "your account is less secure and you can't use features that require a higher level of security." An owner of an older account who has just now activated two-factor authentication has two weeks to change their mind and return to older security settings.
If you have an older account, recently activated two factor authentication, and you're within the two week period for turning it off again, you should check for an email from Apple for a way to do this. If you don't see one about this, look in your junk mail folder.
I think the real question now is why you are having to authenticate 20 times per day. Typically you should only have to authenticate once per device until you do something like completely erase a device. For more about that see Two-factor authentication for Apple ID - Apple Support
