# User Switching
Multiple users and the ability to switch between them is controlled by Settings -> System -> Multiple Users.
## Entry Points
### Quick Settings
In the QS footer, an icon becomes available for users to tap on. The view and its onClick actions are handled by [MultiUserSwitchController][2]. Multiple visual implementations are currently in use; one for phones/foldables ([UserSwitchDialogController][6]) and one for tablets ([UserSwitcherActivity][5]).
### Bouncer
May allow changing or adding new users directly from they bouncer. See [KeyguardBouncer][1]
### Keyguard affordance
[KeyguardQsUserSwitchController][4]
## Components
All visual implementations should derive their logic and use the adapter specified in:
### [UserSwitcherController][3]
* Contains the current list of all system users
* Listens for relevant events and broadcasts to make sure this list stays up to date
* Manages user switching and dialogs for exiting from guest users
* Is settings aware regarding adding users from the lockscreen
## Visual Components
### [UserSwitcherActivity][5]
A fullscreen user switching activity, supporting add guest/user actions if configured.
### [UserSwitchDialogController][6]
Renders user switching as a dialog over the current surface, and supports add guest user/actions if configured.
