Use your web browser and navigate to the Facebook home page. If you are not already logged in, you will see the welcome screen. In the upper-right corner of the Facebook home page, there will be a field for your email address. Enter the email address you used to create your Facebook account.  If you don't have a Facebook account, see this guide to create one. If you have a phone number associated with your account, you can log in with it as well. You will need to enter your password that you created in order to log in. If you forgot your password, click the “I forgot my password” link below the sign-in fields. If you are using your own computer, you may want to check the “Keep me logged in” box. This will bypass the logon process in the future and take you straight to your news feed. If you are on a public or shared computer, you should leave this unchecked for privacy reasons. You should be taken directly to your news feed. If you have login verification enabled, you will need to enter the code that Facebook sends to your phone.
