Q: Google Password

I'm having issue with logging into my google account in the mac.

It was working good until I changed my password in google and now on everytime I open calendar or other app that uses my google account like email too, they ask me for the password and I input that correctly and the windows disappear and nothing happen and it repeat again and ask me for password again.

I tried and put wrong password and it won't go through but with the correct password it go through but I won't get any update and it ask me again.

I also delete the account and setup it again, and it won't work.
