android keeps asking for google account to be reset?

[AC Question]

I have an android phone and the warning triangle at the top keeps asking me to log into the google account - Account Action required, my googlename then appears after clicking this i get - Couldn't sign in / you typed incorrect password or your account has changed Retype your password . If forgot your password and need to recover your account click here.
try again
cancel

I have changed the password and can still access the google account from a computer but this keeps coming up on the phone and it stops access to the google account from the phone, any suggestions would be appreciated
