General steps; menu names vary. California Franchise Tax Board's own guide has the exact screens.

  1. Sign in to California Franchise Tax Board and open your account's security settings. Look for two-step verification or two-factor authentication. California Franchise Tax Board's help pages show the exact screens.
  2. Add your phone number and enter the code California Franchise Tax Board sends, to confirm it.
  3. Save the backup codes. Keep them in your password manager or print them; they're your way back in if you lose your phone or key.
  4. Ask your mobile carrier for a port-out PIN or number lock, so nobody can move your number to their SIM.
