Invitation only. If you already have an account, type your address. The first time, you need the six-character code your administrator gave you.
No public sign-up. After the first day: a code by email, then your authenticator.
We sent a code to your address. It is valid for a few minutes.
Your administrator gives you the address and a six-character code. Both at once, because they were handed over together.
The code works once. Then you set up your authenticator, and after that the six digits from it are all you ever type, plus a code emailed to this address on the web.
Catalyst needs a second step before it will show any company data. Scan this with Google Authenticator, 1Password, or whichever app you use.
Cannot scan? Enter this key by hand:
Open your authenticator app and enter the six-digit code for Catalyst.
