Accounts & Passwords

Recover and secure a compromised Apple ID, including changing the password, removing unfamiliar devices and trusted numbers, checking purchases and Family Sharing, using iforgot.apple.com when locked out, waiting through Account Recovery if needed, reporting unauthorized purchases, checking Find My and iCloud activity, understanding Recovery Key risk, and changing reused passwords elsewhere.
