## Your flow credentials file is encrypted using a system-generated key. If the system-generated key is lost for any reason, your credentials file will not be recoverable, you will have to delete it and re-enter your credentials. You should set your own key using the 'credentialSecret' option in your settings file. Node-RED will then re-encrypt your credentials file using your chosen key the next time you deploy a change.

Did you see this notice in the node's readme on github?

See [https://github.com/deldrid1/node-red-contrib-firebase/issues/28](https://github.com/deldrid1/node-red-contrib-firebase/issues/28) - unfortunately, this repo is no longer maintained and is known to not work with the latest versions of node-red / Firebase. Perhaps you can take up the cause - if you are up to the challenge and want to submit a complete PR or a new repo that wants to take this npm package name, please submit a PR or File a Pull Request and I will be happy to review.
