Needs no phone number registration. – Signal - Private Messenger Review

When can we register without a phone number?? Until this app allows registering with a username or email address instead of phone # it fails at its core mission of private communications. Needs default disappearing message timer and use up less screen space when using disappearing messages. Requiring a phone number is not in the spirit of zero-knowledge.
