I need help with removing the authorization that users have given to my Google Drive application. Right now when users access my app, they don’t get prompted for permissions because they already approved it before. I want to reset this so that the next time someone uses my application, they will see the permission request screen again and have to grant access from scratch. What’s the proper way to clear these existing permissions and force the authorization flow to start over?
go to ur google account settings and revoke the app access. u can do it here: myaccount.google.com/permissions. when users come back, they’ll have to regrant access. it always works for me!
You can force reauthorization from the developer side by tweaking your OAuth flow parameters. Add approval_prompt=force (older implementations) or prompt=consent (newer OAuth 2.0) when building the authorization URL. This bypasses stored consent and shows the permission screen every time, regardless of previous approvals. I’ve done this when updating scopes or needing fresh consent after major app changes. Just remember - this hits all users, not specific ones. You’ll want to decide if you need this selectively based on user accounts or app versions.
You can handle this through your app’s token management instead. Just delete the refresh tokens from your database when users authorize your app. Without valid tokens stored, your app will automatically redirect users to reauthorize when they try to access it. This gives you way more control than forcing consent for everyone at once. I used this method when we had to migrate user permissions after changing our scope requirements. Users whose tokens we cleared had to reauthorize, but everyone else kept working normally. Just make sure your error handling is solid so the redirect works smoothly when tokens are missing.
