One would think that if one came up with a password that is unique and that couldn't possibly be hacked into, it would be easy to remember forever. But no: The Globe-News requires us to change our e-mail password every three months or so, so now that's different from all the other password-protected online functions. When I first joined a credit union, I used my office long-distance code as my password. Now, our long-distance carrier required a different password, so the original is obsolete. Security personeel recommend you not write down your password lest it fall into unsavory hands. But if you don't, you'll have problems getting into your e-mail, your online baqnking, your facebook account, your blog account, etc.
And some sites give you three chances to remember your password. If you can't do it in three attempts, it blocks your access.
There's enough in this world to make me crazy; the Internet doesn't have to add to the process.
