Password best practices in 2026
·7 min read
The single most important factor in password strength is length. A 16-character random password is exponentially harder to crack than an 8-character one with symbols.
Rules of thumb: • Use 16+ characters for general accounts, 20+ for email and banking. • Mix upper, lower, digits and symbols. • Never reuse passwords across sites. • Use a password manager — your brain is bad at remembering high-entropy strings. • Enable two-factor authentication wherever possible.
Generate cryptographically random passwords using our Password Generator at /tools/password-generator. It uses crypto.getRandomValues for true randomness and never sends anything to a server.
