I am not sure if the pass phrase copying issue is a bug or something that is permanant, but If I can't copy over my 12 word passphrase on Counterwallet.co, that is a deal breaker for me. I don't want to use an offline wallet, and there is no way I am going to retype 12 words just to login each time.
Copy and paste into the passphrase window should work. If it's not working for you, it's a bug. What browser are you using?
Also, we are adding a feature into the next release that allows you to produce a link with your (AES) encrypted passphrase attached to it, such as:
http://counterwallet.co/#U2FsdGVkX18jgB3A2XqnaBHpelqd+rVUE/9FHE7cHkCP3gpNXOxzhM/FDNKclYAdNcSLfKPKvi+vEx/yjhWVVQ==The encrypted passphrase is never sent to the server (since it comes after the '#' in the URL). Instead, Counterwallet will display a dialog where you enter a simplier password (which you will set, and which will be used to decrypt the passphrase itself).
This will make logging in as easy as pasting in your special login URL (or using a bookmark), and then typing in a shorter, secondary password that you set yourself. However, you'll still get the full security of the 12 word passphrase, and it won't force us to hold any extra data server side, AND, if someone saw your URL, they wouldn't be able to access your wallet without knowing your custom password.
