About the Secure Password Generator

Strong passwords are long and random. This tool uses the browser cryptographic random generator, which is far safer than patterns people invent.

When to use it

Use it for new accounts and store the result in a password manager. Longer is better than clever.

Why length matters

Each extra character multiplies the number of possible passwords. A random 20-character password using letters, numbers and symbols is far beyond practical guessing, while an 8-character one can be attacked much faster.

Random beats clever

People pick predictable patterns such as names, dates and swaps like @ for a. Attackers try those first. A generator has no habits, so its output has no pattern to exploit.

How to store passwords

Use a reputable password manager so you only need to remember one strong master passphrase. Never reuse a password across sites, because one breach would expose every account that shares it.

Add a second layer

Turn on two-factor authentication wherever it is offered. A password manager plus two-factor authentication protects against most common account takeovers.
