A technique in a wireless mobile device for use in enabling service sessions with a host service via a wireless network is described. The device receives a host login credential from the host service, and saves it in memory. The device detects a logoff trigger for logging off from an enabled service session with the host service. In response to detecting the logoff trigger, the device performing the following actions. The device prompts with, in a display, an entry screen having a field for entry of a device login credential for use in logging on to a subsequent service session with the host service. The device receives, via a user I/O subsystem, the device login credential in response to the prompting, and saves it in memory. After receiving and saving the device login credential, the device logs off from the enabled service session with the host service. After the logging off from the enabled service session, the device detects a login trigger for logging on to the subsequent service session with the host service. In response to detecting the login trigger, the device authenticates the saved device login credential with the saved host login credential. |
