• Writing your passwords on a piece of paper (prone to theft, destruction and loss, and it’s not convenient if you don’t have the paper with you).
• Storing your passwords in an unencrypted file on your computer (also prone to theft and destruction, and it’s not convenient if you travel).
• Using the same password on every site. Some sites will not store your password securely. If it’s stolen, a hacker will check to see if your password works at other sites, with depressing consequences if that works.

There are multiple online services that will store your passwords, but I have personally used and can recommend the following:

• PassPack — Be sure to read all about it before signing up so you can reassure yourself that it’s safer than your current method of remembering passwords.
