Since I work with a number of different customers and access multiple Salesforce.com instances, I have to keep track of a bunch of usernames and passwords. Rather than write it all down and type in the username and password on the login screen, I keep a bookmark for each login that puts me right into Salesforce.com without having to type in the username and password.
To do this, you want to start your bookmark’s URL with the standard login page. Make sure and use HTTPS.

You can then add parameters for your username and password. For example, if your login in email@example.com and your password is qwerty, the rest of your bookmark’s URL will contain the following:
The ? is used to start tell the browser that name/value pairs follow. You should put a & between each name/value pair. pw is the name for the password parameter and un is the name for the username parameter.
Putting it all together, your bookmark’s URL would be:
NOTE: Do not save these bookmarks on sites like del.icio.us. Since your password is in the URL, everyone could see it. Del.icio.us is a public bookmarking system. Keep these bookmarks closely held.
