# Verify matrix-commander "device"

For emoji verification to work, the matrix-commander user needs to be at least in one room.
Enter the room on Element and goto 

* Room Info -> People -> select matrix commander user -> Security -> sessions -> matrix-commander session
* verify with emojis

## Credential information location

matrix-commander expects the following files to be in place for the user to be able to
send/receive messages

credentials.json - $MACO_BASE_DIR/.config/matrix-commander/credentials.json 
           store - $MACO_BASE_DIR/.local/share/matrix-commander/store
