Password managers eliminate the credential reuse vulnerability that makes automated credential stuffing attacks — the industrial-scale exploitation of breach-exposed passwords against other services — effective against the majority of internet users whose email addresses have appeared in at least one breach database. The user experience of a password manager is simpler than the password habits it replaces once the initial setup is complete, the free options available including Bitwarden provide fully adequate security with no cost barrier, and the combination of unique strong passwords and two-factor authentication that password manager adoption enables represents a security posture that eliminates the most common category of account compromise affecting ordinary users. The gap between the security most people have and the security a password manager provides is wide, and the infrastructure to close it has never been more accessible.
