Important ones from there are these:
Password Security: https://www.google.com/get/googletips/card/create-a-better-password-than-password/detail/
Account Security: https://www.google.com/get/googletips/card/protect-your-account-and-your-selfies-from-hackers/detail/
Adn Account Security: https://www.google.com/get/googletips/card/make-sure-your-account-is-secure-with-a-quick-check-up/detail/

Of course the other obvious ones are:

Don't EVER give your password to anyone.
Don't use the same password on more than 2 to 3 service, preferably never on more than one.

Password Manager
I strongly recommend LastPass as a password manager over Chome's native feature. (https://lastpass.com/) I've been a premium member for sometime now and have reviewed the security policies and they're pretty solid. and as Google recommended, I'd suggest using Google authenticator as a two-factor authentication method for LastPass and for site's like Argonath forums always use at least a random 12 alphanumeric password, I use 20+ but that's a bit over the top.

I tried the LastPass and it's somehow epic. I recommend this to all of you out there.

Yep, I've been using Lastpass for a few years, it really is pretty cool, plus you can look up your passwords from a web browser or a phone if you're not at home too, so yea, would recommend it.
