Methods and systems for maintaining reachability of a messaging application

A non-transitory computer-readable medium storing instructions, the instructions comprising instructions to:

• provide messaging services to a first user account logged into a messaging application running on a client device;
• receive a request at the messaging application to log a second user account into the messaging application;
• perform a log-out operation to log the first user account out of the messaging application in response to the request;
• provide a token for the first user account, the token providing limited access to the messaging services for the first user account while the first user account is logged out of the messaging application;
• perform a log-in operation to log the second user account into the messaging application in response to the request;
• and
• maintain reachability of the messaging application by a messaging server associated with the messaging services from a time of the request through a time of completing the log-in operation, the maintaining comprising receiving a notification of a message addressed to the first user account, the message received at a messaging server during a time period between the time of the request and the time of completing the log-in operation.

A system comprising:

• a memory configured to support a messaging application running on a client device;
• a messaging component configured to provide messaging services to a first user account logged into the messaging application;
• a logout component configured to perform a log-out operation to log the first user account out of the messaging application in response to the request, and to provide a token for the first user account, the token providing limited access to the messaging services for the first user account while the first user account is logged out of the messaging application;
• a login component configured to perform a log-in operation to log the second user account into the messaging application in response to the request;
• and
• messaging logic configured to maintain reachability of the messaging application by a messaging server associated with the messaging services from a time of the request through a time of completing the log-in operation, the maintaining comprising receiving a notification of a message addressed to the first user account, the message received at a messaging server during a time period between the time of the request and the time of completing the log-in operation.
