Hello I got email asking me to sign in or I’ll lose my acct since I not used it. I never had to do this before and didn’t know if it was a scam.. I thought I didn’t think I signed up until I tried getting support and seen I had acct I guess so was that email legit ??

My other question is why can’t I save my password on this account on my iPhone so I don’t have to keep signing in? Thanks
