@darylsun the main benefit is you can securely message someone you only know by their online accounts or websites. It also lets you prove your account is associated with a website or another account officially. For example, my Keybase account proves cryptographically that I run the privacytools.io site and my Reddit username is /r/JonahAragon.
If you aren't like, even a semi-public figure the proofs probably don't make sense.
@joey @darylsun Keybase and Signal are both built on standard encryption platforms though, so security-wise it's fine. Wire, Signal, and Keybase are probably equally secure and significantly better than something like Telegram.
Signal is certainly easier (at least on Android) because you can set it as your default SMS app, which is sweet for getting less technical friends/family on Signal.
@darylsun ...But you can still use a Keybase account with no proofs added if you wanted to securely message someone else who has a Keybase account, and you aren't aware of any other forms of E2EE communication to get in touch with them over. Because at least you know that Keybase is E2EE.
Otherwise, no better than Wire or Signal or whatever.
