Your identity
Prove a player is yours by putting a one-time marker in its Topdeck display name. Own several accounts? Claim each one, then merge them into a single profile.
How verification works
1. Pick your player and get a one-time marker.
2. Add the marker to that account's Topdeck display name. Only the owner can — that's the proof.
3. Press Verify. We check the live name directly — no waiting.
4. Remove the marker once claimed. The link is keyed on your player ID, not your name.
Claimed on another device? Re-verify from here — proving the name again hands management to this browser.
