What is Tor exit relay?
The last hop of the Tor network, where anonymised traffic re-enters the normal internet and appears to come from.
A Tor exit relay is the last server in a Tor circuit, where the anonymised traffic leaves the Tor network and reaches its destination on the normal internet. To the destination, the connection appears to come from the exit relay's IP address.
The list of exit relays is public, so defenders can recognise Tor traffic. Seeing a login from an exit relay says the user chose to hide their location, but it does not identify who they are.
