Why do I keep getting an error that my password is wrong?

[AC Question]

keep getting an error that my password is wrong.

For quite a while now, whenever I try to log into the store, Google tells me my password is wrong. I have followed the instructions to reset my password and it works for that session, but then when I go to log in on another day, Google tells me that password is wrong. I write everything down, so I am not going by memory. I have no idea how to solve this. This happens on my phone, Asus transformer pad, and my PC
