Yes. The way I do it is to #1 Use Firefox and #2 When Firefox asks you to Save the Username and Password permanently I choose to do so.
This web site is kinda weird though. I combined 2 types of websites into one. Simple Machines forum and the Drupal CMS. They both really need their own logins and for you to register 2 times and are not related to each other whatsoever. But I had a person help me combine the 2 (to make this full website) made it so members could only register once. It is still a bit buggy, when you log in for the first time on a computer you need to login 2 times. Then after that it will log you in all the time as long as you use Firefox and allow Firefox to save your Username and Password.
As soon as I get some extra money I am going to hire a programmer to fix this small site issue since I am not smart enough to fix it on my own.
