How to use react and capacitor with android AccountManager and apple KeyChain


We are trying to use react.js with ionic and there is almost no word about how to reach mobile platform account management [AccountManager | Android Developers] and (AccountManager  |  Android Developers) and Storing Keys in the Keychain | Apple Developer Documentation.

Couldn’t find anything even for angular.

We found this very old cordova-npm-plugin-kunder-accountmanager project.

Did I miss something important in search… ???

Store/save credentials ability is desperately important feature for all apps with backend…

Can somebody please point me to any documentation on howto manage user credentials on mobile platforms with react and ionic ?

kind regards
