By default, Element will create encrypted DM rooms if the user you are chatting with has keys uploaded on their account. For private room creation, Element will default to encryption on but give you the choice to opt-out.
Set the following on your homeserver's
/.well-known/matrix/client config:
{
"io.element.e2ee": {
"default": false
}
}By default, Element strongly encourages (but does not require) users to set up Secure Backup so that cross-signing identity key and message keys can be recovered in case of a disaster where you lose access to all active devices.
To require Secure Backup to be configured before Element can be used, set the
following on your homeserver's /.well-known/matrix/client config:
{
"io.element.e2ee": {
"secure_backup_required": true
}
}The settings above were first proposed under a im.vector.riot.e2ee key, which
is now deprecated. Element will check for either key, preferring
io.element.e2ee if both exist.
