Change your password
If you suspect that someone else might have access to your account, please change your Grammarly password by going to the Account page. Resetting your password will log out all devices that might be connected to your account. It is important that you choose a strong and unique new password. Also, if you were using the same password for other services, we advise you to reset it for those services as well.
Enable two-step verification
To prevent this type of issue from happening in the future, we recommend enabling two-step verification. With the feature turned on, you will be required to enter an additional six-digit code when logging in to your account. To learn how to set up two-step verification, please see this article.

If you are still concerned about unauthorized access to your account after following the instructions above, please let us know.
