Here are a few tips to help secure your online gaming accounts from hackers:

1. Choose a strong password that includes a combination of letters, numbers, and special characters, and one that you don’t use for any other accounts.
2. Change your passwords often, at least every three months.
3. Enable two-factor authentication (2FA) if it's available.
4. Avoid clicking on links or downloading files from unknown sources.
5. Be cautious when providing personal information over the web or email.
6. Be aware of what you post online, especially in relation to your gaming accounts.
7. Be aware of what permission you are granting to apps, websites, and extensions when giving them access to your account.
8. Regularly review any gaming accounts you have for suspicious activity.
