sign in to oc pledge.

Bitcoin wallet (BIP-322) or email + one-time code. No password to forget. Same identity across every .ochk.io subdomain.

§ email + otp

We email you a 6-digit code. No password, and no wallet needed to start. Link a Bitcoin address any time — that is the identity you hold yourself.

> Codes come from the auth host, expire in 10 minutes, and work once.

OC Pledge is a consumer of the OrangeCheck cross-subdomain session minted at ochk.io. The auth API is family-CORS-enabled so this page can call it directly — no redirect, no popup, no tab juggling. Once your wallet signs (or OTP verifies), the .ochk.io cookie lands and every other family product recognises you too.
