# Storing and Removing Tokens

OAuth Tokens **should be stored securely in the client**. 

* **Mobile apps:** Use [Android Keystore](https://developer.android.com/training/articles/keystore) for Android and [iOS KeyChain](https://developer.apple.com/documentation/security/keychain_services) for iOS apps. 
* **Websites:** Store the `access_token` in memory, the `refresh_token` is automatically included in an `httpOnly` and `Secure` cookie with domain `cotter.app` that is automatically included when requesting to refresh token.
