I would worried if I were you. If you had to reset your password means:
1. You password was so old that it needed to be reset.
2. Your email provider changed it's password security threat because it had an unrelated hack that stole other passwords.
3. You here hacked electronically or someone overlooked your password in a business or school place.
4. You used the same username/password on another web site that got hacked.
So maybe you should start using something like
1Password or other password generating/saving passwords.
