To generate a new `SECRET_KEY`, you can use Django's `get_random_secret_key` function.
```python
from django.core.management.utils import get_random_secret_key
new_secret_key = get_random_secret_key()
print(new_secret_key)
```
#### Rotating SECRET_KEY
When you would want to rotate your `SECRET_KEY`, set the new value and put your old secret key value to `SECRET_KEY_FALLBACKS` list. That way the existing encrypted fields will still work, but when you re-save the field or create new record, it will be encrypted with the new secret key. (supported in Django >=4.1)
