Last month, when I was updating my iPhone, Apple automatically turned on two-factor authentication and things have been messed up with my keychain ever since. I tried Googling ways to fix this, but every time I turn on my computer, I get about 8 warnings saying iCloud keychain needs my password. I've tried changing my password in the keychain, but it's still asking. Do you by any chance have any recommendations? It would be greatly appreciated!
