Authentication apps: You can use an authentication app such as Google Authenticator, which gives you two-factor authentication but ties to your physical device rather than your phone number.This includes text messaging (SMS), which is not encrypted. IDs: Don’t build your security and identity authentication solely around your phone number.
It could provide an additional layer of protection. PIN codes: If your phone carrier allows you to set a separate passcode or PIN for your communications, consider doing it.
And remember, your bank, cable provider, credit card company, or other service providers won’t ask for your personal or financial information through an email message. Don’t click on links in email messages from people you don’t know. Fortunately, there are ways in which you, and your service providers, can help protect against becoming a victim of SIM swap fraud.
