Apple ID password bug?

When I’m trying to update apps, it keeps asking to sign in with my Apple ID password. I type it in the first time and it downloads half of the apps needed to be updated. After that, it asks me again, so I type the same thing again, but it comes out wrong. I thought I might of typed it in wrong but it keeps saying “verification failed, your Apple ID or password is incorrect” . I then reset my password but even after I COPY and PASTE the new and old password many times into the text box it still comes out wrong. I also tried rebooting my iPad, signing out of iTunes and signing back in (also the iTunes sign in is successful so that makes no sense), and refreshing the app, but nothing worked. If anyone can help me with this I would be very thankful. (Somehow, I don’t have this bug on my IPhone and I use the same Apple ID).
