+    <string name="device_manager_learn_more_sessions_inactive">Inactive sessions are sessions you have not used in some time. Removing inactive sessions can improve performance, and make it easier for you to identify if a new session is suspicious. In addition, inactive sessions continue to receive encryption keys and so may pose a security or privacy risk if an unauthorised person is able to access the session.</string>
+    <string name="device_manager_learn_more_sessions_unverified">Unverified sessions are sessions that have logged in with your credentials but not been verified via cross-verification from a verified session, or using your passphrase. You should make especially certain that you recognise these sessions as they could represent an unauthorised use of your account. If you do recognise them, you should verify them as this allows your contacts to see that the new login is really you.</string>
+    <string name="device_manager_learn_more_session_verified">This session has logged in with your credentials and then been verified, either using your secure passphrase or by cross-verifying from another verified session. This means it holds encryption keys for your previous messages, and confirms to other users you are communicating with that the session is really you.</string>
+    <string name="device_manager_learn_more_session_rename" tools:ignore="UnusedResources">Other users in direct messages and rooms that you join are able to view a full list of your sessions, including which are verified and unverified. This provides them with confidence that they are really speaking to you, but it also means they can see the session name you enter here.</string>
