MFA (Multi-Factor Authentication)

Multi-factor authentication requires users to provide two or more independent verification factors from different categories: something you know (password, PIN), something you have (phone, security key), and something you are (fingerprint, face). This ensures that compromising one factor isn’t enough to gain access.

MFA dramatically reduces the risk of account compromise. Microsoft reports that MFA blocks 99.9% of automated attacks. Even if a password is phished or leaked in a breach, the attacker still needs the second factor.

For teams, MFA should be mandatory for all critical accounts. A team password manager can store TOTP seeds alongside passwords, making it easy for team members to use MFA on shared accounts without passing codes back and forth.
