 1. **SSH Public key**: self-explanatory. Add your public key to your user attrset under `sshPubKeys`.
 2. **Wireguard device**: each wireguard device has two parts: the public key and the IP addresses it should have in the wireguard network. The pub.solar wireguard network is spaced under `10.7.6.0/24` and `fd00:fae:fae:fae:fae::/80`. To add your device, it's best to choose a free number between 200 and 255 and use that in both the ipv4 and ipv6 ranges: `10.7.6.<ip-address>/32` `fd00:fae:fae:fae:fae:<ip-address>::/96`. For more information on how to generate keypairs, see [the NixOS Wireguard docs](https://nixos.wiki/wiki/WireGuard#Generate_keypair).
 
+One can access our hosts using this domain scheme:
+
+```
+ssh barkeeper@<hostname>.wg.pub.solar
+```
+
+So, for example for `nachtigall`:
+
+```
+ssh barkeeper@nachtigall.wg.pub.solar

+- [SSH access to host `nachtigall`](../administrative-access.md#ssh-access)
+
+Run following after SSH'ing to `nachtigall`.
+
+Credentials for the following command are in keepass. Create a keycloak
+config/credentials file at `/tmp/kcadm.config`:
+
+```
+sudo --user keycloak kcadm.sh config credentials \
+  --config /tmp/kcadm.config \
+  --server https://auth.pub.solar \
+  --realm pub.solar \
+  --client admin-cli
+```
+
+Get list of accounts without a verified email address:
+
+```
+sudo --user keycloak kcadm.sh get \
+  --config /tmp/kcadm.config \
+  users \
+  --realm pub.solar \
+  --query emailVerified=false \
+  > /tmp/keycloak-unverified-accounts
+```
+
+Review list of accounts, especially check `createdTimestamp` if any accounts
+were created in the past 2 days. If so, delete those from the
+`/tmp/keycloak-unverified-accounts` file.
+
+```
+createdTimestamps=( $( nix run nixpkgs#jq -- -r '.[].createdTimestamp' < /tmp/keycloak-unverified-accounts ) )
+
+# timestamps are in nanoseconds since epoch, so we need to strip the last three digits
+for timestamp in ${createdTimestamps[@]}; do date --date="@${timestamp::-3}"; done
+
+vim /tmp/keycloak-unverified-accounts
+```
+
+Check how many accounts are going to be deleted:
+
+```
+jq -r '.[].id' < /tmp/keycloak-unverified-accounts | wc -l
+```
+
+```
+jq -r '.[].id' < /tmp/keycloak-unverified-accounts > /tmp/keycloak-unverified-account-ids
+```
+
+Final check before deletion (dry-run):
+
+```
+for id in $(cat /tmp/keycloak-unverified-account-ids)
+  do
+    echo sudo --user keycloak kcadm.sh delete \
+      --config /tmp/kcadm.config \
+      users/$id \
+      --realm pub.solar
+  done
+```
+
+THIS WILL DELETE ACCOUNTS:
+
+```
+for id in $(cat /tmp/keycloak-unverified-account-ids)
+  do
+    sudo --user keycloak kcadm.sh delete \
+      --config /tmp/kcadm.config \
