This requires a dedicated phone number to receive +# the verification code text message for the new Signal account. Google +# Voice numbers are useful here. +# +# Linking gives the host running irssi the same access to the account +# (such as reading messages, changing account settings, and more) as the +# Signal app has on your phone or computer. +# +# - Register a new account: +# - signal-cli -u +12128675309 register +# - Retrieve verification +# - signal-cli -u +12128675309 verify VERIFICATION-CODE-FROM-SMS +# +# - Link to an existing account: +# - signal-cli link -n $(hostname) +# - qrencode -o device-link-qrcode.png 'tsdevice:/?uuid=...' +# - View device-link-qrcode.png. +# - Scan the QR code with the Signal app +# (Settings -> Linked Devices -> Link New Device). +# +# 3.
