Will Google Authenticator stop a sim-swap attack from compromising my Coinbase?



  • If I use Google Authenticator for Coinbase, and someone sim-swaps my phone number and gains full access to my email account, can they drain my Coinbase account?

    They would be in control of my email, sms, and phone calls.



  • It will depend on how Coinbase protects the account from the loss of the 2FA code. If you can get past the 2FA by saying "send me an email/text instead", then 2FA does not protect you at all in this case.

    If the 2FA code cannot be bypassed so easily, then 2FA can protect the account better from SIM-swap attacks.
