Sign in with an authenticator app as well

1. Go to Profile, open settings and tap Security.
2. Tap Set up an authenticator app and scan the code with Google Authenticator, Microsoft Authenticator, 1Password or Authy (or type the key).
3. Type the 6-digit code it shows and tap Turn on.

From then on, after your email code, Phuse asks for the code your authenticator app shows. That goes for the business dashboard on your computer too. Turn it off with Remove on the same screen.
