xChk

TVP | Login with xChkLogin

Carry verified trust into your app

Standard OAuth 2.0 / OpenID Connect — but the product isn’t another login button. It’s a signed verification portfolio (helpdesk passes, interviews, passkeys, consistency) that users consent to share. You decide what evidence is enough; xChk signs what they’ve already built on the platform.

Good fit
  • You already send people through xChk (helpdesk, interview, attestations)
  • High-risk gates need history, not just “authenticated at T₀”
  • Verification-first apps — e.g. crabbyed.com
Not a fit — use Google / Microsoft instead
  • Generic signup for cold internet traffic
  • You only need email + profile (no verification history)
  • Users with no xChk sessions — portfolio will be empty

New apps start unverified — users see a warning on the consent screen until your app is verified (domain proof, business verification). Contact support to verify.
