A concise, practical guide to signing in to BlockFi safely: step-by-step access, multi-factor setup, how to troubleshoot sign-in problems, and recommendations to keep your account and crypto secure.
To sign in, navigate to BlockFi's official website and click Sign In. Enter your registered email address and password, then complete any additional verification steps configured on your account. Always confirm you are on the correct domain and that the page uses HTTPS with a valid certificate before entering credentials.
Use a unique, long password for your BlockFi account—ideally a passphrase of 12+ characters combining words, numbers, and symbols. Avoid reusing passwords across critical accounts such as email, exchanges, and financial services. A reputable password manager simplifies generating and storing robust credentials securely.
Enable MFA immediately after logging in. Time‑based one‑time passwords (TOTP) via authenticator apps (Google Authenticator, Authy, or similar) are recommended over SMS where possible due to SIM swap risks. Store your MFA backup codes in a secure, offline location so you can regain access if you lose the device hosting the authenticator app.
Your email is a primary recovery channel. Secure it with a unique password and its own MFA. If your email is compromised, attackers may initiate account recovery flows. Regularly review your email account’s security settings and recovery options to reduce the risk of unauthorized access to your BlockFi account.
Phishing attempts mimic BlockFi’s login UI or support messages to trick you into revealing credentials or recovery codes. Verify sender addresses on emails, hover over links before clicking, and avoid logging in via links sent in unsolicited messages. When in doubt, visit the official BlockFi domain directly by typing it into your browser.
If you enter the correct credentials but cannot sign in, try these steps: clear your browser cache, disable browser extensions that may interfere with authentication, attempt a different browser or device, and confirm BlockFi service status via official channels. If you forgot your password, use the Forgot password flow to request a reset link sent to your registered email. For MFA device loss, use backup codes or contact official support channels — never provide your recovery codes to anyone who contacts you unsolicited.
Sign out after using shared devices and review active sessions where BlockFi offers that capability. Keep your operating system, browser, and security software up to date to reduce exposure to known vulnerabilities. Avoid storing passwords in shared browsers and disable automatic form‑filling on public computers.
For users managing significant balances, consider segregating assets across multiple accounts and using cold storage or hardware wallets for long‑term holdings. Regularly export and verify account activity and enable IP allow‑lists if BlockFi supports them. Implement organizational policies for teams that separate duties and require multiple approvals for large transfers.
Contact BlockFi support only through channels listed on the official website. Support staff will never ask for your password or private keys. If you receive a suspicious message claiming to be BlockFi, report it and verify through official social accounts or the support portal before following instructions.
