This article explains how to find out when a friend last logged in on Facebook. If a user has logged out of the chat, this information will not be available.
Steps
Step 1. Open Facebook
The icon looks like a white "f" on a blue background and is located in the app drawer or on the home screen.
If you are not logged in, enter your credentials and tap "Log in"
Step 2. Tap the contacts icon
It depicts a white human silhouette with three horizontal lines and is located at the top right.
Step 3. Scroll down until you find the person you are looking for
On the screen that opens you can see the last access of the contacts you spoke with recently and a list of friends currently online. The last login time is to the right of each user's name.
- If you see a green dot next to the user's name, it means they are active at the time (or have been in the last few minutes).
- If you see a number accompanied by the letter "M" (minutes), "H" (hour) or "G" (days), it indicates the last login on Facebook of the user in question.
