--- title: Security sidebar: Handbook showTitle: true --- It is critical that everyone in the PostHog team follows these guidelines. We take people not following these rules very seriously - it can put the entire company and all of our users at risk if you do not. ## Password Managers You **must** make use of a password manager; it simply isn't possible to use appropriate passwords securely without one. PostHog uses [1password](https://1password.com/) for storing all passwords. ## Password Strength Please use strong passwords for everything. Use the 1password password generator that comes with the app in all cases. Do not repeat passwords across different sites. ## Dual Factor Authentication You should enable dual factor authentication for any account where the option is available, especially those which are core to your work.
