Friend asked me about Signal, triggered by the ever growing concerns about US big tech.

They're not technical and I said I'd look into it for them.

I've never used it and upon install it asked for

1. Permissions to see my "contacts"

2. A phone number.

What? Why?

Can Signal be used without these?

@rzeta0 πŸ’‘ Why does Signal need your phone number? πŸ“±
Your number acts as a secure identifier linked to your public key, ensuring end-to-end encryption remains seamless. πŸ”
By optionally syncing contacts, Signal easily connects you with friends already on the platform without storing your address book on their servers. Private & convenient! ✨

@rzeta0
Is "trust" enough for privacy? πŸ€”
Signal uses secure enclaves (Intel SGX) to hash numbers so they "can’t see" your data. But should we rely on server-side tech at all?
Alternative apps like Olvid or Session require NO phone number, removing the link to your physical identity entirely.
Is crypto-math enough, or is "zero data" the only true security? πŸ”βœ¨
