Passwords

AHHHHHHH! I am very tired of passwords and logins and such. I spent half this week trying to do projects for class but would forget what my password was or what the login was suppose to be. I know one should write them down somewhere, but that list is who knows where and I haven't always been good about writing them down. There are a few variations of one password and login that I use so that I can try and remember it but there are still those times when I can't remember if I should use a login in name or my email (and which one). Sometimes I even get the security questions wrong- really??? I can't remember the answer to a security question about me?!?!? : ) What would be really nice is to have one login and one password that works to get into everything. For instance it opens a page and from there you can access all your accounts. I realize that maybe that isn't the "safe" way to do it, but it would save some time and frustration when all you want to do is finish your homework and get it turned in! : )
