You can improve the security of your Facebook account by getting an alert when someone tries logging in from a device or web browser we don't recognize. These alerts will tell you which device tried logging in and where it's located.
To get alerts about unrecognized logins:
- Scroll to the bottom of Facebook and tap Settings & Privacy.
- Click Security and Login.
- Click Get alerts about unrecognized logins.
- Choose where you want to receive your alerts, such as your email account or with a Facebook notification from a recognized device.

Facebook Touch in Chrome OS Sidebar. Keeping Facebook open all the time is not hugely practical. So I opted to turn on desktop notifications for Facebook through Chrome. This way I keep on top of pointless pressing updates but without the need to keep checking the site itself. Google Chrome is a lightweight browser that is free to download for Windows, Mac OS X, Linux, Android, and iOS. Follow this guide to get it downloaded and in.

- When you receive a login alert, you can tell us if you recognize the login activity by clicking or tapping This was me.
- If you don't recognize the login activity, click or tap This wasn't me and we'll help you reset your password and secure your account.
- You can save a device or browser to your list of trusted browsers or recognized devices. This way, you won't get alerts about the computer or mobile device you usually use to log into Facebook. Don't choose this option if you're using a public computer (such as one in a library or cafe).
- A list of recent devices that have logged into your Facebook account can be found in your Security and Login Settings.
