Signal can only be registered to one mobile device at a time. But you can link Signal to Signal Desktop.

A security risk due to National Security letters, which require giving up data to the US state, and making it illegal to disclose that.
Con Unreliable notifications
Sometimes messages won't be received if the Signal app has been closed for a long time or hasn't been opened after booting the device.
Con Cannot use with VPN
Because Blokada works by using an internal VPN to act as a filter, it is not possible to use Blokada if you're using an actual VPN.
