Yes, you can use Signal without sharing your personal phone number. Here’s how I did it.

”It’s important to maintain control of this phone number."

I strongly feel that this is false.

~~If someone trys to register with an existing number then it wont work if its already being used.~~
Im not sure on this^
Better to enable a security pin if you are concerned.
The traditional phone system involvement is annoying.

Got a source for that? There have already been multiple contradicting sources posted saying this isn't true.

I cant find any information that discusses the security risk. But it would seem that this transfering all content to the owner of the phone number is a standard feature.
So, maybe its not discussed because it doesn't frequently happen.
It doesnt seem like a trustworthy way to ensure users' content remains secure.
