You've got a working Tor service, but over time you may wish to reset or otherwise adjust it.
## Secure Your Hidden Services
Tor allows you to limit which clients talk to your hidden services. To take advantage of this, you should do the following:
1. Request your Tor V3 Authentication Public Key from your client. (In [GordianWallet](https://github.com/BlockchainCommons/GordianWallet-iOS), it's available under the settings menu.)
2. Go to the appropriate subdirectory for your Bitcoin hidden service, which if you used Bitcoin Standup is `/var/lib/tor/standup/`.
3. Go to the `authorized_clients` subdirectory.
4. Add a file called `[anything].auth`. The `[anything]` can really be anything.
5. Place the public key (and nothing else) in the file.
Once you've added an `.auth` file to the `authorized_client` subdirectory, then only authorized clients will be able to communicate with that hidden service. You can add ~330 different public keys to enable different clients.
