 Any Cwtch user can turn the app on their phone or computer into an untrusted server to host a group chat, though this is best for temporary needs like an event or short-term coordination, because the device needs to stay powered on for it to work. Medium-term untrusted servers can be set up on a spare Android device that can stay on, and longer-term servers can be self-hosted on a VPS if you know Linux system administration. Once the server exists, contacts can be invited to use it. You can create a group chat with only two people, which enables asynchronous direct messages.  
 
->**Note**: [**Briar**](https://briarproject.org) is another application which works in a similar way (with peer-to-peer and Tor), and uses the [Bramble Transport Protocol](https://code.briarproject.org/briar/briar/-/wikis/A-Quick-Overview-of-the-Protocol-Stack) (BTP). The main distinguishing feature of Briar is that it continues to function [even when underlying network infrastructure is down](https://briarproject.org/how-it-works/). It was [audited in 2017](https://code.briarproject.org/briar/briar/-/wikis/FAQ#has-briar-been-independently-audited). Unfortunately, Briar Desktop does not yet work with Tails or Qubes-Whonix, because it cannot [use the system Tor](https://code.briarproject.org/briar/briar/-/issues/2095). Unlike Cwtch, to connect with a contact on Briar, you must both add each other first. You can either exchange `briar://` links or scan a contact’s QR code if they are nearby.

->**Note**: You may have heard of **XMPP** (formerly called Jabber). XMPP has similar security properties to Matrix, but many clients don't support end-to-end encryption (via the OMEMO protocol) by default. Configuring a client properly is non-trivial. XMPP and Matrix leak similar amounts of metadata, but OMEMO has never been formally audited like the Matrix encryption protocol.

The new entry will be under "Data (Block) Devices", typically `sys-usb:sda` is the one you want (`sda1` is a partition and would need to be mounted manually).

 1) Memorize diceware passphrases of 7-10 words for anything that is not stored in a KeePassXC database
 2) Generate passwords of 21 random characters for anything that can be stored in a KeePassXC database. Maintain an offsite backup of your KeePassXC database(s) in case it is ever corrupted or seized. 
 
-> **Tip**: Diceware passphrases can be easy to forget when you have several to keep track of, especially if you use any irregularly. To mitigate against the risk of forgetting a diceware passphrase, you can create a KeePassXC file with all "memorized" passphrases in it. Store this on a LUKS USB, and hide this USB somewhere offsite where it won't be recovered during a police raid. You should be able to reconstruct both the LUKS and KeePassXC passphrases if a lot of time has passed. One strategy is to use a memorable sentence from a book - this decrease in password entropy is acceptable if the USB is highly unlikely to ever be recovered due to its storage location. This way, if you ever truly forget a "memorized" passphrase, you can access this offsite backup.
