Overview

This guide explains how to log into your BlockFi account, set up and manage two-factor authentication (2FA), resolve common login problems, and perform account recovery. Whether you're using the BlockFi web app or mobile app, the steps and tips below will help you safely regain access and protect your cryptocurrency holdings.

How to Sign In (Web & Mobile)

  1. Open the BlockFi website at https://blockfi.com or launch the official BlockFi mobile app.
  2. Click or tap Sign In (top-right on web or on the app welcome screen).
  3. Enter the email address associated with your BlockFi account and your password.
  4. If 2FA is enabled, enter the code from your authenticator app or SMS (if SMS-based verification was used).
  5. After successful verification you will land on your dashboard.
Tip: Save your authenticator backup codes in a secure location (not on the same device) to simplify recovery if your phone is lost.

Troubleshooting — Common Login Problems

  • Forgotten password: Use the Forgot Password link on the sign-in page. Follow the emailed reset link and create a new strong password.
  • Authenticator code not accepted: Ensure your phone's clock is synced (time drift breaks TOTP codes). Re-sync the clock in your authenticator app settings or re-add the account using your saved backup key.
  • No access to email: If you cannot access the recovery email, follow BlockFi's account recovery process (see Account Recovery below).
  • Account locked: Multiple failed attempts may temporarily lock account access. Wait a short period and try again, or contact support for help.

Two-Factor Authentication (2FA) — Best Practices

2FA dramatically improves account security. BlockFi supports authenticator apps like Google Authenticator, Authy, and other TOTP apps. Avoid SMS 2FA if possible because SIM-swap attacks can bypass SMS codes.

  • Use an authenticator app (TOTP) and keep backup recovery codes offline.
  • Store your backup seed in a secure password manager or printed safe deposit box.
  • When changing devices, transfer or reconfigure your authenticator app before wiping the old device.

Account Recovery

If you’re locked out and cannot use the standard password reset or 2FA, open a support ticket with BlockFi. Be prepared to provide identity verification details (photo ID, selfie, email, recent transaction history) as directed by the support team.
