 <note warning>When logging into a new device (a different browser, a new phone, your fridge), you will only get access to your already encrypted messages //after// verifying the new session. This is explained below (and most easily done if you use Element on your phone).</note>
+==== The somewhat short story ====
+When using encryption in a room (or direct chat) all messages in that chat will be encrypted. Everyone of your clients (e.g. the webclient at meet.physik.fu-berlin.de or Element on your phone) will have a session with its own keys. This is mostly transparent to you as a user, but you must always hold either of the following to be true:
+    * Have one running session (in a browser on your computer, on your phone, wherever), so that new sessions can authenticate against the running session (cross-signing, described below), or
+    * have access to your recovery passphrase (that you should create when you first log in) to recover your encryption keys when you log into a new session and have no other running sessions to authenticate against.
+If either of this is the case, you will keep access to your old encrypted messages, so generate a recovery passphrase and save it in your password safe.
