+### Remove Session Keys {: #removing-session-keys }
+
+Before removing your session keys, you'll want to make sure that you've stopped collating and left the candidate pool. To stop collating, you'll need to schedule a request to leave the candidate pool, wait a delay period, and then execute the request. For step-by-step instructions, please refer to the [Stop Collating](/node-operators/networks/collators/activities/#stop-collating){target=_blank} section of the Moonbeam Collator Activities page.
+
+Once you have left the candidate pool, you can remove your session keys. After which, the mapping bond you deposited will be returned to your account.

 ## Setting an Identity {: #setting-an-identity }
 
 Setting an on-chain identity enables your collator node to be easily identifiable. As opposed to showing your account address, your chosen display name will be displayed instead.
