Sign in to the app

First time signing in or haven’t signed in for 90 days? Or, did you sign out? To keep your account secure, you’ll complete a 2-step sign-in process.
  1. Sign in to NumberSync from your tablet. You’ll get an alert, but don’t worry. This is the start of the 2-step sign-in.
  2. Look for a text from us that has a passphrase. We’ll send it to the primary phone number linked to your user ID
  3. Reply to that text with the passphrase.
  4. Sign in to NumberSync again after you get a confirmation text.
