- Be careful about sharing your mobile phone number. Consider using a different number, such as a landline, with businesses like grocery stores and dry cleaners. Limit sharing your mobile number anywhere it might be posted publicly or to many people, such as on social media, email signatures, and phone lists.
- Add additional authentication measures to other accounts, such as financial accounts, and don’t use your mobile phone number as a source of security and authentication. For example, enable app-based two factor authentication on your accounts whenever possible. (These include Google Authenticator or Authy, and soon more apps and online services will use ZenKey, a joint venture of the three major US wireless carriers.)
Security experts recommend a number of additional safeguards for managing cryptocurrency.
- Learn about the security measures available and make sure you are using the most secure authentication methods.
- If you want to be particularly careful, store cryptocurrency in “cold storage” – an environment without online access.
- Don’t store cryptocurrency wallet credentials online. Instead, write them down and keep them in a secure physical location.
- When choosing financial investments and services, consider that some are protected from theft and fraud, others are not. For example, cryptocurrency accounts are not insured from theft like other types of traditional financial accounts. If cryptocurrency is stolen from you, it most likely cannot be recovered.
- Protect all your financial accounts and information.
If you believe your SIM card has been swapped without your consent, report it to your carrier right away. Also, contact your financial institutions and email provider to protect your accounts.
