Definition
A password (or passphrase) is a secret you prove to a systemâusually with a username or emailâto show you are allowed to use an account. It should be known only to you (and stored with care).
Password vs PIN vs passphrase
- PIN â Often numeric and short. See our PIN generator.
- Passphrase â Longer series of words or tokens, often easier to type. Try the passphrase generator.
- Random password â Mixed characters, high entropy. Use the strong password generator or 20-character tool.
