Quick Answer: What Is a Password Generator?
A password generator is a tool that creates random passwords using selected rules such as length, letters, numbers, and symbols. A strong random password is usually harder to guess than a short or reused password.

What Makes a Strong Password?
Strong passwords are usually long, unique, random, and not reused across multiple accounts. A longer password or passphrase is often easier to protect than a short predictable password, especially when it is stored safely and paired with two-factor authentication where available.
Password Length Guide
| Password Length | Best Use | Notes |
|---|---|---|
| 8 characters | Minimum for many websites | Not ideal for important accounts. |
| 12 characters | General accounts | Better when mixed with random characters. |
| 16 characters | Important logins | A stronger option for email, admin panels, and financial accounts. |
| 18+ characters | High-value accounts | Useful when the service allows longer passwords. |
| Passphrase | Memorability | Good when it uses multiple unrelated random words. |
Random Password vs Easy-to-Remember Password
| Password Type | Best For | Example Style |
|---|---|---|
| Random password | Password managers and important accounts | Random letters, numbers, and symbols. |
| Easy-to-remember password | Manual typing when allowed | Longer phrase-style passwords. |
| Passphrase | Memorability | Several unrelated words. |
| Reused password | Not recommended | The same password across accounts. |
