 If you are logged into another session, e.g. on your phone, it's easiest to click **Use another login**. There are multiple ways how this is handled, which depends on where the other session is running, e.g. Element on phones will allow you to do this via scanning a QR code. All methods do require, though, that you have the device where the other session is running on //at hand// otherwise the whole process will block waiting for you to do something on the other device, which is hard to do, if it's far away. If you are logged into another session, e.g. on your phone, it's easiest to click **Use another login**.

 +==== I'm asked to authenticate every time I open my browser. What am I doing wrong? ====
 +
 +You will need to reauthenticate (that means: type in your recovery passphrase or use another session to authenticate your new one) whenever you log out of [[https://meet.physik.fu-berlin.de]] or your browser loses its cached data and cookies. That means, if you are especially privacy conscious and configure your browser to delete cookies and caches on exit, your running session will die as well.
 +
 +[[https://meet.physik.fu-berlin.de]] only sets first party cookies and uses the local browser cache for some of its data. Whereas third party cookies are definitely are a privacy problem (and Firefox' Enhanced Tracking Protection can really help you with that out of the box even without [[https://addons.mozilla.org/en-US/firefox/addon/ublock-origin/|uBlock Origin]], which is something everybody should use), can deleting first party cookies be a tad overzealous, since the server you are contacting sees everything you do with it anyway. Deleting the cookie and cached data interferes with how the client at [[https://meet.physik.fu-berlin.de]] operates. You can resolve this problem by granting an exception to deleting this data in your browser's preferences.
 +
 +On Firefox you can do this on the //Privacy & Security// page of the settings in the section //Cookies and Site Data//. If you have checked //Delete cookies and site data when Firefox is closed//, this is the reason for needing to reauthenticate after every time you close Firefox. Click the //Manage Exceptions// button (//Manage Permissions// on older versions) and enter both [[https://meet.physik.fu-berlin.de]] and [[https://meet.physik.fu-berlin.de|http://meet.physik.fu-berlin.de]] and save your choice.
