Browsers LocalStorage gets reset after login with social media

[Satish-Lakhani]

Hi, I'm using satellizer social media login for user registration/login process in my web app.
Here i'm setting few tokens in windows local storage before social media login. After successful response of social media login from satellizer, browser local storage gets reset, means the token which i've saved before login, gets wiped out. Is this expected behaviour with satellizer? How can i prevent this behaviour?

Thanks
