Is it true that enabling multi-factor authentication blocks more than 99 percent of automated account takeover attacks?
Partly. Several sources describe MFA as an extra layer of security against credential stuffing, brute force and account takeover fraud, while one peer-reviewed paper stresses that MFA is not bulletproof and can itself be attacked. None of the retrieved items reports the specific figure that MFA blocks more than 99 percent of automated account takeover attacks.
