Best practices
- Use 14–20+ characters; passphrases are great (four+ random words).
- Mix lower/upper, digits, and symbols — but avoid predictable substitutions (e.g.,
a→@). - Avoid dictionary words, names, dates, keyboard patterns, or company/product names.
- Never reuse passwords; enable 2FA wherever possible.
- Prefer a password manager to generate & store unique passwords.
