Password generators: length, entropy, and storage

Create strong passwords in the browser and learn why generation is only half the problem.

Strong passwords are long, random, and unique per site. A generator removes human bias—no birthdays, no keyboard walks. Client-side generation means the candidate password never transits to a server during creation.

Length beats complexity theater

A 16+ character random password from a broad alphabet beats an 8-character password with forced symbols. Entropy grows linearly with length.

  • Use 16–24 characters for user accounts
  • Use 32+ for API keys and machine secrets
  • Include upper, lower, digits, and symbols when the site allows

After generation

Store passwords in a reputable password manager—not a text file, not a Slack DM. Rotate credentials when vendors disclose breaches. Never reuse production passwords in staging.
