Yes, automatic login in facebook is possible, provided you are already logged in your google account in the same internet browsers like google chrome, facebook and internet explorer. This way your online life could little easier as you don’t have to enter the facebook password and username every time you go to facebook login page, you will be automatically logged in.
The best thing you can do is making your browser remember the password, in order to make logging in easier for you. But then it might not be possible for you to do the same when you are at your workplace then what can be the other smart way to do that. Keeping this thing in mind Facebook has come up with a new feature with the help of which you will be able to log into your Facebook account without entering the credentials even if that system does not remember your password.
You will have to link your Facebook account with another account by going to the setting option and then adding another. Procedure to do the same has been mentioned later in the post. Once you link any account to your Facebook profile then you will not have to enter the credentials to enter Facebook profile, if you have already entered that linked account. For example, if you have linked your Google account with Facebook, then once you open you Google account you will not have to provide credentials while accessing your Facebook account.
Auto Login In Facebook
Here is the procedure to do the same. Please follow this step by step.
Login to your account as you used to by providing your login credentials and then click on the drop present on the right top corner of the screen (as mentioned in the screenshot).
Then click on the option named Account Settings (as mentioned in the screenshot).
You will see a page as mentioned in the screenshot below, now click the highlighted link.
Now select any of the options available in the dropdown and then enter you Facebook Password.
Then Facebook will ask permissions to use that linked accounts information. Once you provide the Access to Facebook, your account will be linked and then you will not have to enter the username and password for Facebook, when you have already opened that linked account on that system.
But then it creates a vulnerability of your account to get hacked because now the hacker know you Google Password, then he or she might hack your Facebook account too. Please let us know if you face any trouble or need further information related to this feature of Facebook.
