Authenticator apps generate time-sensitive, two-factor authentication (2FA) codes, making it much harder for unauthorized users to access your accounts, even if they have your password. Compared to SMS-based 2FA, authenticator apps are not vulnerable to interception or SIM swap attacks, providing a stronger layer of protection for your digital identities and personal information.
