Entering your Facebook username and password each time you log in is annoying! Luckily you can save your account credentials on your devices via Facebook's settings. This allows you to access Facebook automatically, on your registered devices.
To access your Facebook each time without entering your credentials, you need to change your login settings. This setting will authenticate your device, allowing for a secure connection where you will no longer have to enter your account details to enter Facebook.
Open the app and click on the three horizontal lines at the bottom right of the screen. Select Settings & Privacy > Settings. Next, click Security and login:
Go down to Authorised logins and you will be able to manage the list of authorized devices.
To authorize automatic login on your desktop, go to Facebook and click on the downward arrow at the top right of the screen. Click on Settings > Security and login:
