Why can't I log in?

I had to update my password at Twitter and then Twitbin recognized it, and logged me in.

I still have that problem. I changed my PW at Twitter, but Twitbin still won't let me in.

I am working from a private Laptop with no restritions for twitter and my twitter-name is NorDoc - not very strange, is it?

I have this same problem. I can access Twitter directly and through other clients, such as TwitKit, but TwitBin gives the following error:

Unfortunately we couldn't verify your username or password, please enter them below and try again

Clearly something's not right, and it seems specific to TwitBin.

Could this be a firewall problem? Twitbin works fine at work with my browser configured to use the company proxy. However, at home, it chokes where I have my own router/firewall setup. I don't understand why this should be an issue. Twitkit works fine everywhere, so I can only assume Twitbin works differently.

i have this problem too. it won't let me log in with info that is definitely correct.
now it has me blocked out entirely because it says i've entered the wrong info too many times. this is ridonkulus. it shouldn't take 2 hours to try to log-into a new app.

I have the same problem. Once I try entering my info and login, it gives me the "Unfortunately we couldn't verify your username or password" error and then won't let me do anything else. The little "working" icon keeps spinning as if it's trying to do something and there is no way to make it stop. Stupid, stupid extension!

What should take 10 seconds for a moron fails miserably and forced me to remove the extension. IF you can fix this simple authentication issue...

I'm having the exact same problem. Any solutions?

I'm also having this problem, despite a firefox update, and a twitbin update. I even posted here a month ago and still haven't heard of a solution

I figured out what was wrong on my end: I had my cookies settings wrong. Once i told Firefox to accept all cookies -- including 3rd party cookies -- everything was cool.

If you think this might be your problem, too, you can change your settings (in Firefox) by going to "Options" (from the "Tools" drop-down menu) and choosing the "Privacy" tab.

I solved the problem by deinstalling twitbin. Everything's fine now.

Allow third party cookies. This solved the problem for me.

by deleting all existing twitter cookies and trying to relogin I was finally able, but then on my first attempt to tweet I was told that "sorry twitter has reached it's hourly request limit on my account, bla bla bla"

no there are no other twitter services on my laptop
