FAQ
Common questions
What does verification prove?
It proves the same identity controls linked accounts and can approve real-time verification requests.
What does it not prove?
It does not prove legal identity, intent, or transaction safety. It proves control continuity of linked accounts.
How does security work without sharing secrets?
Verification uses signed proofs and account-control checks so counterparties can verify identity continuity without seeing sensitive credentials.
What if a verify link is forwarded?
A forwarded link alone is not enough for live verification. New requests still require owner approval in real time.
What account details become public?
Only selected account identifiers are shown on a verify page. Account linking proves control, not full account access.
Can I change emails or auth methods later?
Yes. Add and verify the new account first, then remove the old one. You can rotate linked providers and devices over time.
What is included in Free?
Free includes up to 3 linked accounts at a time and 3 live verifications per month. Pro expands capacity and adds recovery controls.
What does linking X or LinkedIn prove?
It proves your identity can authenticate the same social account during linking, which strengthens continuity signals for verifiers.
