Best Passphrase Practices

Do's

  • Use 5-6 random words from a trusted wordlist.
  • Insert separators (hyphens or spaces) for readability.
  • Add optional numbers/symbols for services that require them.
  • Store passphrases in a secure manager instead of memory.
  • Regenerate when a service reports a breach or compromise.

Don'ts

  • Use personal info (names, quotes, lyrics).
  • Choose predictable sequences or keyboard walks.
  • Reuse the same passphrase across multiple accounts.
  • Share passphrases over chat, email, or text.
  • Skip breach checks—verify important secrets regularly.

Check if a passphrase was exposed

Use our privacy-first Breach Test to see whether a passphrase appeared in known leaks. We only transmit a hashed prefix.
