Any way of having safari remember user names and passwords

Although not free, I use 1password (1passwd.com). Assuming you're using a Mac, you can do all the setup on the computer and then it transfers to the Touch or iPhone. For added security it prompts you for your password to open 1password, and then it handles usernames and passwords for you after that. Also has a wallet feature for information like credit cards and such which can then be opened within Safari on the Touch (again, with a username and password required to get into the interface).

It depends on the site.
Some sites only need cookies.
More secure sites need something more powerful.
1Password is cool, I own and use it, but the 1Password alpha is just that - alpha.
It works, but not perfectly yet.
