Account Security and Suspicious Activity

Contact support immediately if:

• You suspect your account has been taken over.

• You see activity you do not recognize.

• Your password, API key, token, device, or session may be compromised.

• You receive a suspicious email, SMS, phone call, or chat claiming to be from Clear Street.

• Funds, positions, orders, or account settings appear changed without authorization.

Do not paste sensitive information into chat, including passwords, API keys, bearer tokens, OAuth credentials, session cookies, one-time passcodes, recovery codes, bank information, government ID numbers, or full account identifiers.

For suspected security events, contact support so the issue can be reviewed through the appropriate secure process.
