After the latest update to the Android version of Spotify, I have been having issues with getting my Android device to authenticate my last.fm account. Therefore I am also having problems scrobbling my music. Recently I also changed my password at last.fm due to the security breach they experienced.
The problem is as follows: Every time I enter my new password in my Android device to authenticate my last.fm account, Spotify "shortens" the password every time I navigate away from the settings page. It seems that only the first 10 letters or so of my password is constant. Therefore I always get a password error when Spotify attempts to scrobble music to last.fm.
I have NOT experienced these problems on my desktop using the ordinary Spotify client, which scrobbles just fine.
Solved! Go to Solution.
The settings page on the new Android client doesn't work the same way as on the desktop client. After you have typed the last.fm password you must hit enter on the Android keyboard for it to be accepted. On the desktop client it happens as soon as you leave the password text field or leave the settings page. Maybe this is the confusion here? Try typing the password and hitting return in the Android client and see if it helps.
Well, finally got it to work. I had tried using the android keyboard before but to no avail. As it happens, it was a trailing space at the end of the user name that was the problem. Thanks everyone!!
