# Class TokenStore.DefaultStorageTokenStore

java.lang.Object
com.codename1.io.oidc.TokenStore.DefaultStorageTokenStore

All Implemented Interfaces:
  `TokenStore`

Enclosing interface:
  `TokenStore`

public static final class TokenStore.DefaultStorageTokenStore extends Object implements TokenStore
The default store. Serialises the token JSON to `Storage` under a `"cn1.oidc."`-prefixed key. Convenient and zero-config, but not encrypted-at-rest -- the underlying storage on Android is the app's internal files directory, which is sandboxed but not protected against a rooted device with backups enabled.
