I can log out as follows: At login time, I store the token in localStorage and in the logout method, I did as follows:

//LOGOUT GOOGLE
    const token = await AsyncStorage.getItem("@ellot:googleAccessToken");
    if (token) {
      try {
        await AuthSession.revokeAsync({ token }, { revocationEndpoint: 'https://oauth2.googleapis.com/revoke' });
        await AsyncStorage.removeItem("@my:googleAccessToken");
      } catch (error) {
        console.log('ERROR XXX', error)
      }
    }

Logout with Expo - Auth0 Community

December 1, 2020 - Hi there, I’m facing similar problems to the following unresolved issues: I’m able to log in to auth0 using the example here: https://github.com/expo/examples/tree/master/with-auth0 I’m using the following to try to log the user out await WebBrowser.openBrowserAsync( ${myAuth0Domain}/v2/logout?client_id=${auth0ClientId}&returnTo=${redirectUrl}, ) When I do so and check the logs in the auth0 console, I see a successful logout.

Thank you for sharing this! Works great with Auth0, within a few modifications (endpoint, clientId, and setting an appropriate path in makeRedirectUri).

r/reactnative on Reddit: How do you fully logout (remove a specific cookie?)

February 14, 2023 -

I'm using Azure B2C to authenticate, and once the user logs in B2C adds a cookie to the system browser.

The problem I'm having, after the users logs out of the app, and goes to re-login, they're automatically authenticated without being prompted for their credentials.

I'm using expo and can't seem to figure out how to fully "logout."

I've tried revokeAsync with AuthSession, as well as React Native Cookies to attempt to remove the cookie with no success.

How is this usually handled?

Any help appreciated!

do u mean webview or what? it's depend on your code. usually login - logout use API endpoint for example for login use yourwebapiendpoint.com/login and POST method send data JSON {username:"username",pass:"pass"} the return you will get auth token if success. the auth token then used in this endpoint as bearetoken set up if in postman yourwebapiendpoint.com/profile to logout u just need to remove their credential token in database

I don't use those, but typically, revoking is done on the backend. Is there an endpoint you can call to log out?

The auth.expo.io proxy is deprecated. Hard to pinpoint the cause but this error is often associated with cookies not being able to be set properly, which can happen if the browser has especially strict cookie settings. One thing that’s confusing is your screenshot shows a desktop browser instead of the mobile on-device browser. The currently recommended solution is react-native-fbsdk-next for Facebook login. https://docs.expo.dev/guides/facebook-authentication/

It sounds like you are being logged in via silent authentication. This does indeed use a session cookie. To fully logout the user you must clear the cookie, or use the recommended method of utilizing the /logout endpoint.

You can test this by logging in with an incognito/private browsing window, or by clearing the cookie before clicking the login button the second time.

August 20, 2020 - Hi @hannes.hesse , This has shifted down my list of priorities lately, and I haven’t figured out a solution yet. I was doing some digging during the holiday break, and I think the solution lies somewhere in the expo AuthSession docs. Specifically, my next shot would be to mess around with some of the methods exposed there, specifically AuthSession.revokeAsync(). I still haven’t attempted this solution, but I think the issue has to do with cookies being passed back from the expo WebBrowser th...
