Keybase uses public key cryptography to ensure your messages stay private. Even they can’t read your chats.

Keybase works for families, roommates, clubs, schools, churches, groups of friends, or any other communities.

Keybase can connect to public identities, also. You can join forces with communities from Twitter, Reddit, and elsewhere.

Keybbase also can be used to publicly verify your identities so others can not fake being you.

Keybase can store your group’s photos, videos, and documents with end-to-end encryption.
