We use ‘consistent’ to emphasize that the intermittent use of any security practice is as bad as not using one at all. Once you develop a threat model and a strategy to defeat it, you must apply that strategy every time you engage in private activities. -

Every user must understand your group’s Threat Model and consistently use the same security practices. -

When you first log in, your chat roster on the right side of the screen will be empty. From the menu at the bottom you can Add Contact. Just start typing and it will automatically search for existing users on the server, or you can type in the XMPP address of external users. -

To stay connected when you’re not logged in to Gibberfish, you can also connect to the server directly using an XMPP-compatible client such as Adium, Pidgin, or one of many mobile apps. -

The chat server is also reachable as a Tor “onion service” on port 5222. Ask your administrator for your server’s Tor address. -

However, when chatting with users outside your server, you have no guarantee of privacy unless you and your contacts use an end-to-end encryption plugin such as “OTR”. Most chat clients support end-to-end encryption, and have guides to help you understand and enable it. -

It is difficult, but possible, for your data to be intercepted by resourceful adversaries while in transit. For this reason we do not recommend syncing your data without carefully considering your Threat Model and your security practices. -

TWO-FACTOR AUTHENTICATION -

Once you’ve changed your passphrase, we also strongly encourage you to enable Two-Factor authentication (“2FA”). This involves installing an app on your mobile device that generates a unique 6-digit code you must enter each time you log in. For someone to hack your account, they would need to know your passphrase and physically possess your phone. This combination keeps you more secure. Because Gibberfish is part of the Nextcloud ecosystem, you can use the Nextcloud 2FA app. This app supports FreeOTP, which can be downloaded in the app store for Android and iOS devices. -

If you’re not already in the habit of doing so, it would be a good idea to store your passphrases in a key vault like KeePass. Key vaults make it easy to securely remember all your passphrases. You will need to lock your key vault itself with a Diceware generated passphrase. In addition, we strongly recommend you enable full-disk encryption on the device storing your key vault. -
