It is a good idea to regularly conduct a security check-up on your bConnected Google account. Here is how to perform a check-up, and remove any undesired apps connected to your account.
- Open your bMail account.
- Click your profile picture then click My Account

- Under the Sign-in & security section, click Connected apps & sites

- Locate Apps connected to your account and click MANAGE APPS.
- A list of Apps connected to your account appears. Review the list for any apps that should not have access. Click "REMOVE" on any of the apps that you do not want anymore. Don't worry about unintentionally removing access for any app that has legitimate access to your account, since you can always add it back later.

- A confirmation message appears that the app can no longer access your account.

- Repeat the steps until all suspicious/undesired apps are removed.
