Android M - usb / password keychain

Here is the workflow from iOS that I am trying to achieve on Android:

  • The user launches the application for the first time and successfully logs in with credentials (the API is sent for verification).
  • Invitations to register with Touch ID
  • User selects YES => Username / Password stored in Keychain
  • The user logs out, closes and restarts the application.
  • Invitations show to use fingerprint for authentication
  • User uses fingerprint for authentication => Username / Password is retrieved from Keychain and then sent to API

Is there an Android equivalent of the iOS Keychain API? From what I read, Keystore seems to only be able to store keys and certificates.
