Account locked frequently

I have a lot of devices, but none of them are unknown to me. I loathe two-factor ID. It adds no significant security, apart from psychological, and it just adds an extra step of difficulty to the situation. I had it and opted out after a couple of weeks because of the extra hassle. The additional security is marginal and does not improve my basic complaint, which is having to re-enter my password multiple times on each of my many devices. If they can all be locked in one fell swoop, they should all be UNLOCKED the same way, with one entry. I had to enter my password FOUR TIMES this morning just in Music on this iMac and I STILL can't check for downloads. And when the iOs keyboard won't pair with a locked Apple Watch, it is a nightmare. If, say, the password includes a character like "o" (mine doesn't) you CANNOT use Scribble to easily differentiate between "o" "O" and "0". The entire process is enormously cumbersome and unnecessary.

I do appreciate your help and advice. Thanks.

That's correct, yes. Instead of entering my childhood [whatever] I was entering a passcode, sometimes sent to a phone that was not always with me. (I do not always have my work phone with me.) My point is, I am not the one mis-entering a password enough times to get my account locked. Perhaps if my log-in was something other than my email address, which is public, I would be okay, but I was told that my log-in cannot be altered. Again, thank you for your time.
