About "BlockFi Login"

Referencing BlockFi Login* in this document means the process by which a user authenticates to their crypto service account to view balances, trade, borrow, or move assets. Secure access combines something you know (password), something you have (device or MFA token), and sometimes something you are (biometrics). Understanding these components helps you reduce risk when accessing financial services online.

Pre-Login Checklist

Before attempting to log in, prepare a safe environment:

• Use a personal, updated computer or trusted mobile device — avoid public terminals.
• Confirm that you are accessing the official service through verified channels; do not follow unverified links.
• Have your MFA method ready (authenticator app, hardware key, or other approved method).
• Ensure your password manager is up to date and storing unique, strong passwords for financial sites.

Strong Authentication Practices

Implementing robust authentication reduces the chance of unauthorized access. Recommended approaches include:

• Use an authenticator app (TOTP): Authenticator applications generate time-based one-time passwords and are preferred over SMS for most users.
• Consider hardware security keys: FIDO2/WebAuthn keys provide high-assurance authentication and protect against phishing attacks effectively.
• Enable biometric locks on devices: Where supported, device biometrics add a convenient layer of protection but should be combined with strong passwords.

Recognizing Phishing and Fraud

Phishing remains a primary attack vector against account holders. Beware of attempts to trick you into revealing credentials or MFA codes. Defensive steps include:

• Inspect the sender's email address and avoid clicking links in unsolicited messages.
• Manually type or bookmark the verified login URL instead of following links.
• Check for HTTPS and valid certificates, but also verify domain spelling carefully — attackers often use lookalike domains.
• Never share one-time codes, passwords, or recovery phrases with anyone claiming to be support.

Session & Device Management

Good session hygiene limits exposure if devices are lost or compromised:

• Sign out of sessions you no longer need and periodically review active sessions from your account security settings.
• Use unique browser profiles for financial activity to reduce the chance of cross-extension interference.
• Enable device encryption, strong OS passwords, and automatic lock screens on mobile devices.

Account Recovery & Backups

Understand the recovery options offered by your service and protect recovery artifacts:

• Store backup codes or recovery methods offline in a secure location; do not store them in cloud notes or screenshots.
• Follow verified recovery procedures if you lose access; be prepared to verify identity through secure channels.
• Avoid third-party recovery services — use only the exchange or service's official process.

Troubleshooting Login Problems

If you experience difficulties signing in, try these safe steps:

• Confirm time synchronization on your device if using time-based MFA — incorrect device time can cause token mismatches.
• Clear your browser cache or attempt sign-in from a private/incognito window to rule out extension conflicts.
• Try a different, known-good device or network to determine whether the issue is local.
• Contact official support channels if standard recovery flows do not resolve the issue; avoid sharing sensitive information in public forums.
