Yes, hackers can sometimes bypass 2-step verification (2FA), particularly if it uses SMS. Attacks like SIM swapping can intercept SMS codes, and phishing attacks can trick users into revealing their codes. To enhance security, it's advisable to use app-based 2FA methods, like authentication apps or hardware tokens, which are significantly more secure than SMS-based 2FA. Regularly updating passwords and avoiding sharing sensitive information can also help protect against these vulnerabilities.
