Methods and systems for population of user identifiers based on nearby devices are disclosed. One or more user identifiers are entered into a first electronic device. When the first electronic device is in proximity to a second electronic device, and a user prepares to log on to the second electronic device, the one or more user identifiers from the first electronic device are retrieved by the second electronic device and presented to the user for selection. The user identifiers may be displayed in a prioritized state based on particular factors. Sharing policies for particular user identifiers may be set based on user input. The user can then select one of the presented user names for logging on to an account with the second electronic device.
