# Custom Master Key

For compliance or backup purposes, you can provide your own master key:

```bash theme={null}
# Generate a key
openssl rand -base64 32

# Use during init
kfl init --master-key "K7gNU3sdo+OL0wNhqoVWhr3g6s1xYv72ol/pe/Unols="
```

<Note>
  If `MASTER_KEY` already exists on the worker, the provided key is ignored. This prevents accidental data loss from key rotation.
