Today when I tried to login, my old password was not working. Was my account hacked ? Do I need to worry about it.
I was able to reset password as email was not changed.
Are you copy-pasting your password and how complicated is your password if you follow the right security in creating your password, then it is a combination of small letters, big letters, special characters, spaces, and numbers and because of this, you may have mistyped some of the letters because your keyboard could be malfunctioning.
This was my case when I cannot log in.
But if you think that this is not the case then you are right in changing your password, if there's an intrusion you are lucky that the email was not changed.
But do an investigation if you think that there's an intrusion.
