Feature Request: Allow multiple devices to be paired to one extension

[carumusan]

Given the risks of losing a single device whether it be through theft, damage etc it makes sense to have a backup to login. Would make things easier if the extension allowed for multiple phones to be paired and switch between them. Maybe by having a primary device and allowing manual switch when needed.

At the moment I believe the workaround would be to unpair the main device and re-pair the backup, add the backup device to a website, then unpair the backup and re-pair the main device.
