When they announced usernames I thought I will be able to install Signal on my TV desktop (linux) and send / receive messages from to it (links, files, etc).

Now that I know it still needs phone number I assume it will need to be unique so my use case fails.

For the record, I am still a happy Signal user and a monthly supporter, thank you very much.

There's a contact in Signal called "Note to Self" that you can use for this.

I use Signal this way too. It's great for small messages and files. For larger files, you'd want SyncThing.

Just hair splitting obviously but I don’t think it’s really a contact, it’s just what the recipient shows as when you send something to your own number.
