Verification at sign-up isn't enough on its own: phones and accounts change hands. So checks keep going, lightly.
Tier 1: confirm your phone once a month
If you earned anything in the last 30 days, we'll ask you once, at the start of a session, to confirm the same phone number with a code. It takes about ten seconds.
If the number no longer works, you'll move to Tier 0 until you verify a new one. Earnings already made aren't affected.
Tier 2 and 3: a quick face check at random
Now and then, before a question, the app asks for a three-second face check. It checks that the person answering matches the person who verified. Dismissing it three times drops you to Tier 1.
Other times we ask
- Signing in on a new phone, or after reinstalling the app.
- Adding or changing a payout method.
- Changing country.
Why this matters
These checks help us keep to one account per phone at Tier 1, and one account per verified identity at Tier 2. They take seconds if you are using one account. They make it harder, though not impossible, to run many accounts.
