Methods and systems are provided for collecting, storing, and transmitting account information in a matchable form, and for using this information to quickly set up accounts. Account information is maintained and shared between one or more client devices and an intermediate server. Account information can be reconciled locally to determine whether to add or enable an active account or an account proxy to a client device. Account proxies can be quickly enabled by a single user action. The methods and systems allow enabled accounts and account proxies to be removed from a first client device without propagating the deletion to a second client device.
