Abstract: Systems and methods are provided for registering with a given application. The systems and methods include operations for receiving, with a messaging application, a request to authenticate a phone number from the given application, the phone number being input by a user to register an account with the given application; determining that the phone number received in the request matches a user phone number stored in a user account associated with the messaging application; in response to determining that the phone number received in the request matches the user phone number stored in the user account, transmitting a communication from the messaging application to the given application indicating that the phone number has been authenticated; and causing the given application to register the account for the user to enable the user to log into the given application.

Abstract: Systems and methods are disclosed for prioritizing a list of applications. The systems and methods include identifying, with a messaging application, a list of applications that are configured to share authentication information with the messaging application; determining a priority value of each application on the list of applications; generating for display, with the messaging application, a graphical user interface that represents a selection of applications from the list of applications based on the priority value of each application on the list; and for each application represented in the graphical user interface, generating for display a user-selectable option to authorize the messaging application to share authentication information with the respective application.

Abstract: Systems and methods for sharing authentication information are provided. The systems and methods include generating, with a messaging application, a media item using a camera of a client device; identifying a target application that has been authorized by the messaging application to share authentication information with the messaging application; generating a share option associated with the media item for display in a graphical user interface of the messaging application; and in response to receiving a user selection of the share option, enabling the target application to access the media item.

Abstract: Systems and methods are provided for sharing authentication information. The systems and methods include retrieving, with a messaging application, a list of applications that are installed on a user device; searching the list of applications to identify a given application within the list of applications that is configured to share authentication information with the messaging application; and in response to identifying the given application within the list of applications, generating for display within a graphical user interface of the messaging application an option to authorize the messaging application to share authentication information with the given application.
