I have a Nokia Lumia 521, and I am not able to download any apps. I have about 4.0 Gigabytes left of storage on my phone, so that isn't the issue. But, when I try to download an app it says "Cannot sign in, incorrect password". It is annoying, because I deleted some apps on my phone, since they were causing problems.
TL;DR
Can't download apps on my Nokia Lumia 521
