Don?t worry, it?s a new ?feature? of iOS. It?s annoying, so I turned it off.
If you go to passwords in settings you will find them all under ?security recommendations?.
I think they are trying to encourage you to use the 15 character passwords they are so fond of. Which, given you can barely use them even when they are written down, means using Key Chain for everything.
I use two-step for anything involving money.
