How to generate a strong password
To generate a strong password, open the ToolCrix Password Generator, set the length to 16 or more, enable uppercase, lowercase, numbers and symbols, and click Generate. Each password is created with your browser's secure crypto random generator, never transmitted, and ready to copy into a password manager.
Want to create a strong, random password that's actually hard to crack — and easy to generate? This guide explains what makes a password secure and how to generate one for free in your browser using a cryptographically secure random generator. Nothing is sent anywhere.
What makes a password strong
Strength comes from length and randomness, not from swapping ‘a’ for ‘@’. A 16-character random password mixing upper, lower, numbers and symbols has so many combinations that brute-forcing it is infeasible.
Reused and predictable passwords are the number-one cause of account takeovers. A unique random password per account, stored in a password manager, is the single biggest security upgrade most people can make.
How to use it (step by step)
- Open the Password Generator.
- Set the length — 16 or more is recommended.
- Toggle character sets: uppercase, lowercase, numbers and symbols.
- Optionally enable ‘pronounceable’ mode for a memorable-but-strong password.
- Copy your password (it's generated with the browser's crypto API) and save it in your password manager.
What you can use it for
- Creating a unique password for every new account.
- Generating WiFi or router admin passwords.
- Making API keys, database passwords or seed strings for developers.
- Producing memorable passphrases for accounts you type often.
- Bulk-generating a batch of passwords for a team.
How long should a password be?
8 characters is no longer safe. Aim for 16+ characters for important accounts. Each extra character multiplies the number of possible combinations, so length beats complexity. For logins you must type by hand, a 4–5 word passphrase is both strong and memorable.
Tips
- Use a different password for every account — never reuse.
- Store passwords in a reputable password manager, not a notes app.
- Turn on two-factor authentication wherever it's offered.
- Avoid names, dates and dictionary words even with substitutions.
