Cant sign into specific google account

[AC Question]

I have a Samsung Galaxy Ace (GT-S5830) and for some reason it wont let me sign into google account A, I have a secondary account B which works perfectly fine and lets me sign into that but I want to access account A from my phone too. I can perfectly fine sign into account A on multiple different devices, I tried changing the password and that didnt work too. I'm absolutely certain that I type everything correctly as I have retried it about a million times by now. I'm stuck, anyone has any suggestions?

OP here, I tried that but it keeps telling me to change my password which I have already tried twice.

Just found out the problem. Account A had 2-step verification so I needed to use an app password.
