iOS, iPadOS, and macOS detect common patterns used to create memorable passwords, such as using words found in a dictionary, common character substitutions (such as using “p4ssw0rd” instead of “password”), patterns found on a keyboard (such as “q12we34r” from a QWERTY keyboard), or repeated sequences (such as “123123”). Passwords are marked weak if they may be easily guessed by an attacker. Passwords are marked reused if the same password is seen used for more than one saved password across different domains. If a service is breached and passwords are leaked, attackers may try the same credentials on other services to compromise additional accounts. Using the same password for more than one service may leave those accounts vulnerable to a credential-stuffing attack. iPhone Text Message Forwarding security.How iMessage sends and receives messages.Adding transit and eMoney cards to Apple Wallet.Rendering cards unusable with Apple Pay.Adding credit or debit cards to Apple Pay.How Apple Pay keeps users’ purchases protected.Intro to app security for iOS and iPadOS.Protecting access to user’s health data.How Apple protects users’ personal data.Activating data connections securely in iOS and iPadOS.Protecting user data in the face of attack.Protecting keys in alternate boot modes.Encryption and Data Protection overview.UEFI firmware security in an Intel-based Mac.Additional macOS system security capabilities.
