§ signin

sign in to your vault.

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

§ email + otp

We email you a 6-digit code. No password. The federation provisions a custodial wallet for you in your browser. Best path if you don't have a Bitcoin wallet yet — graduate to self-custody anytime by adding your BTC address from your account dashboard.

> OTP delivered by the auth host. Codes expire in 10 minutes and are single-use. Rate-limited 5 starts/hour/IP.

OC Vault 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 — there's no redirect, no popup, no tab juggling. Once your wallet signs (or your OTP verifies), the .ochk.io cookie lands and every other family product recognises you too.
