    I need help to add an additional parameter of a password or secret key to our Firebase database. This will change the stock google signup methodology, which will then be served to our backend to get a ubiquity JWT token from our backend API. We skipped the question of what platform to use to host the Firebase database, and decided to go with JavaScript for the programming language for making the changes. Finally, we have chosen to store the additional parameters in plain text, rather than encrypted. We are looking for someone who can help us make these changes to the Firebase database using JavaScript and make sure that the additional parameters are securely stored in plain text. If you have experience doing work like this, please let us know how you can help!
