Passwords & Authentication

A strong password is long and unpredictable, length matters more than clever substitutions like "P@ssw0rd", which attackers' cracking tools already expect and check for automatically.

Example: two logins, one meaningfully safer

Login A: password only
  -> a leaked password (from any breach, anywhere) grants full access

Login B: password + MFA (a code from your phone)
  -> the same leaked password alone is no longer enough to get in

Multi-factor authentication (MFA) adds a second proof of identity beyond a password, a code from your phone, a fingerprint, so a leaked password alone isn't enough to break in. A password manager lets you use a unique, random password per site without having to memorize any of them, removing the temptation to reuse the same password everywhere (which is exactly what makes one breach elsewhere dangerous to you specifically). Enabling MFA is one of the single highest-impact security steps an individual can take, for a small amount of daily friction in return.
