This concern may be unfounded, but I shy away from third-party Twitter applications that require my Twitter password. I do this out of worries that it increases the chance of somebody being able to hack into my Twitter account. If you think that doesn’t make sense, let me know in the comments section.
Given that concern, though, there are quite a few Twitter-related applications that let you do a lot with information that can be gotten without your Twitter password, and I thought I’d begin a “The Best…” of them here. I’m sure I’ve missed a lot, though, so feel free to suggestion additional ones.

Here are my choices for The Best Third-Party Twitter Apps That Don’t Require Your Password:

I may be missing something, but outside of subscribing to your own Twitter feed in your RSS Readers, this appears to be a great way to search for your tweets.

Tweeps Key will…well, it’s complicated. But it’s a cool visualization.
I’ve never really understood why some people are concerned if the people they are following in turn follow them back. I figure I’m following people because I want to, not because I want them to follow me. But, if that is a concern of yours, Friend or Follow will tell you the answer to these questions: “Who’s not following you back on Twitter? Who are you not following back? Who are your mutual friends?”
Who Should I Follow? will give you lots of recommendations.
Follow Cost will tell you how “annoying” you and others are on Twitter.
