Save yourself some grief…
And money and time.
We have many tips on our web site concerning passwords . The number one issue with passwords is remembering them. It's crazy how many computer users I help that tell me, "I don't have a password.", when I query them about their email or Internet password to troubleshoot a problem or setup a new computer. ANY OF US WHO HAVE EMAIL ADDRESSES HAVE TO HAVE A PASSWORD. It may have been years since you had to remember what it is, but at some point you will be asked for it. Use some of the great (and free) software packages available to manage your passwords. Or at the least write them down in a central location; small address books work well, post-it notes, not so much.
