# Reset a firewall's local user database

You can replace the firewall’s local copy of the user database with a copy of the internal user database on the Management Server.

##

If you use the internal user database of the SMC, the user information is stored centrally on the Management Server. When changes are made, they are incrementally replicated to each firewall node to guarantee fault-tolerant authentication. If necessary, you can perform a full synchronization manually.
