Twitter users need a Valet Key for 3rd Party Tools

I’m noticing a lot of Twitter tools requiring the user to enter their Twitter user id and password to use the tool. These tools obviously need the users’ credentials to access the Twitter API and act on behalf of the user.

But am I the only one who is uncomfortable with this? I mean, isn’t the first rule of passwords not to give them out to anybody? Isn’t it?!?!?

Instead it’s become the acceptable practice to enter it into every app requesting it! Correct me if I’m wrong …..
