What can I reach, and how do I turn on two-factor auth?

My access is a mirror, not a settings page: it shows the organizations you belong to, the role you hold in each, and — for an admin — a shortcut back to the people who can see the same things you can. If something looks wrong, that is the first place to check before asking anyone else.

Two-factor auth adds a second step to sign-in: a code from an authenticator app, in addition to your password. Turn it on from Two-factor auth in your Account settings — scan the code with any standard authenticator app and enter the six digits it shows you to confirm.

Once it is on, losing the device is the thing to plan for: keep the backup codes it gives you somewhere other than the device itself. An administrator can help a locked-out teammate back in; nobody can turn someone else's two-factor auth on or off for them.
