Signal Messenger Registration Lock

 



For increased security, you can enable a Registration Lock PIN in Signal. You will be asked to enter this PIN the next time you register your phone number with Signal.

Using a Registration Lock PIN adds an additional layer of verification to the registration process that can help prevent someone from using Signal with a phone number that doesn't belong to them.
