#FAQ
Do I need a phone number for XMPP?
Often no. Many providers allow account creation without phone number and sometimes without email.
Can I message users on other providers?
Yes. XMPP is federated, so cross-provider messaging works like email domains.
Is encryption automatic?
Not always. It depends on client and contact setup. Verify encryption status in each chat.
