Because the car screen exists in a shared space, the profile lock helps each user protect their identity in the car. If a user opts to create a profile lock, they will be required to unlock the car screen every time they start a new drive.\n\nGoogle recommends encouraging all users to create a profile lock. This lock will protect their identities and keep their personal information safe, no matter who uses the car.\n\nRoles \\& process\n----------------\n\nGoogle provides OEM partners with default UX as part of AAOS, including design guidelines to create profiles and profile locks. OEM partners can choose to customize the user experience, similar to similar to how they customize other AAOS UX.\n\n| Google's design role | Vehicle OEM's design role |\n|-------------------------------------------------------|-------------------------------------------------------------------------------------|\n| Provides a default profile experience as part of AAOS | Customizes AAOS profile experience or creates a new profile experience from scratch |\n\nUser journeys\n-------------\n\nUsers interact with their profiles in the car through the following user journeys:\n\n- [Selecting a profile](/cars/design/automotive-os/product-experience/system-ui/profiles/how_profiles_work#selecting_a_profile)\n- [Locking a profile](/cars/design/automotive-os/product-experience/system-ui/profiles/how_profiles_work#locking_a_profile)\n- [Recovering from input errors](/cars/design/automotive-os/product-experience/system-ui/profiles/how_profiles_work#recovering_from_input_errors)\n- [Recovering from a forgotten profile lock](/cars/design/automotive-os/product-experience/system-ui/profiles/how_profiles_work#recovering_from_a_forgotten_profile_lock)\n\nThis section will help you understand these user journeys and how the profile\nexperience in AAOS addresses them, as well as best practices to keep in mind.\n\n### Selecting a profile\n\nThe profile selection screen provides users a way to quickly find an existing profile, or to add a new profile. It's a gateway to helping users control their identities and personalization in the car, and it also offers users a way to protect their profiles in a shared space.\n\nBecause cars generally support multiple profiles, users typically see a single view displaying the full array of profiles.\nIdeally, the profiles are clearly differentiated from each other using design mechanisms such as color, images, or naming\n\n### Locking a profile\n\nAndroid Automotive OS has integrated a car screen profile lock to allow users to protect their identities in the car. Much like a phone screen lock, the profile lock is a unique PIN, pattern, or password that protects the user's profile in the car, giving them access to their personalized settings and infotainment experience.\n\n#### Creating the profile lock\n\nBecause many users already use a screen lock on their phone, it's likely that they will have a learned preference and want to reuse that method with their car screen. Users are given choice and flexibility with access to several simple options to lock their profile.\n\n#### Choosing a preferred lock method\n\nUsers have the option to create a profile lock using whichever method they prefer: PIN, pattern, or password.\nHere, the user specifies a PIN to create a profile lock Here, the user draws a pattern to create a profile lock Here, the user enters a password to create a profile lock\n\n#### Recovering from input errors\n\nTo help users who've made an entry mistake while unlocking their profile, use motion, color or messaging to communicate what went wrong, and how to try again.\n\n#### Recovering from a forgotten profile lock\n\nAt times, users may forget their profile lock, and Android doesn't provide a default mechanism for users to recover or reset this lock. When no reset option exists, it's important to give users another choice to continue using the car's infotainment system.
