android – The way to securely share knowledge between two Flutter apps (credentials)

I’m a little bit bit caught on a topic.. I used to be creating 2 cell purposes with Flutter, every with an authentication system. I want to develop the next performance:

1. I go online to the “A” software, I save my credentials.
2. I open the “B” app, I can discover the account with which I signed within the “A” app. (For instance: On my iphone, if I register with my google account to Gmail, I discover the identical account on all of the google apps on my telephone).

So I’d have to have the ability to retailer the passwords & identifiers securely on the telephone, and solely my 2 purposes might have entry to this “frequent” database. I checked out Hive/ SQFLITE, however I don’t suppose it’s appropriate for this type of performance to share between 2 apps…

Thanks to your assist,
