Signal is centralized and requires a phone number. This is potentially impactful to your anonymity. So, for example if the recipients device is comprised that encryption doesn't mean much and you may be identifiable.

All that said, I use Signal. But it's good to know it's shortcomings.

Edit: added potentially. You could certainly have a number not associated with your identity.

anonymity, privacy, and security are not inclusive of the other and anonymity is not in scope of signal. SimpleX would be a better option if that's your goal, although being in beta still, I can't fully recommend it
