I check the documentation only says never only in vault activities in the quizz tell me is the best option that “Inside a Control Room vault” that other option that consider?
We recommend using the Control Room Vault in production. Locally stored file base secrets are usually only good for development use.
Like @Teppo said, it is best to use the control room vault when running bots in production in the cloud. For testing you can use the vault.json file as discussed here: Use a vault for secrets. If there is a specific use case that you need to cover where control room vault will not work please let us know and we can discuss further.
