Is it possible to secure the data like financial data in a specific device using cloud-db or firebase db and not visible multiple devices
I am not understanding the secure and usecure method, can someone explain it to me with blocks
To explian in few words I want to save my individual clients financial data.
Use firebase db
I tried saving the data and checked on 2 different devices but the data was not secured, it was visible on both devices
You need to do setup block like isAlreadyLoggedIn = true,
and also save this data in Firebase DB with user details and where you are showing details.
If the variable = false
then show data from the Firebase DB,
Else Notifier.ShowAlert.Text(Already Logged in)
I am not good at reading code, can show in blocks method
Okay I try it for you.
That will be helpful
You didn't share your code so we don't know how you coded your app.
I expect you may use the same Tag for all users financial data and if so, certainly anyone can read it all probably. Do you save data with a Tag for each user and require the users to sign in to password protect individual accounts?
Do you encrypt user data and provide a code for each user to encrypt/de-encrypt? Doing so will provide some light weight security.
Please find the solution for your project by me.
This can be your solution.

I will surely try this and let you know,
Thank you 
Sure! try it and let me know if you have any difficulty.
Hi,
I have still not tried this, I will revert you soon
Can we use only the device Id instead of email and password, will this work and how?
Why you need that, this will only allow one device per ID, this will not work as professionally, as if you use device id then why it is necessary to have alreaady logged in feature just get if logged in,
but this is not the professional way, use the professional way I gave you add all blocks to the bag from aia file the paste them to your main project file, this will give you less stress than mine.
Ok,
I will try your way,
Thank you.
