I am creating Mobile APP just to list the records from Firebase real time database and update(Patch) the single field. I have not configured Sign in method. It works fine when i allow all read and write for anyone in firebase security rules.
How can I configure Secure connection for this to list the record and update the field with access token. I searched and found Get ID Token (Firebase auth) function can be used.
I appreciate any help or reference to detailed written information on this
