Why Enable 2FA?

Two-factor authentication (2FA) adds a second layer of security to your account. Even if your password is compromised, an attacker cannot log in without your authenticator app.

Supported Authenticator Apps

  • Google Authenticator (iOS / Android)
  • Authy (iOS / Android / Desktop)
  • 1Password
  • Bitwarden

Enabling 2FA

  1. Go to Account → Security → Two-Factor Authentication.
  2. Click Enable 2FA.
  3. Scan the QR code with your authenticator app.
  4. Enter the 6-digit code to confirm.
  5. Save your backup codes in a secure location.

Logging In with 2FA

After entering your password, you will be prompted for a 6-digit TOTP code from your authenticator app.

Recovery Codes

If you lose access to your authenticator app, use one of your backup recovery codes to log in. Each code can only be used once.

Store backup codes offline — in a password manager or printed and stored securely.

Disabling 2FA

  1. Go to Account → Security → Two-Factor Authentication.
  2. Click Disable 2FA.
  3. Enter your current TOTP code to confirm.

API Access

2FA does not affect API key authentication. API keys bypass 2FA entirely — treat them as secrets.
