How to Generate a Strong Password: From Length to Entropy
Weak passwords are the number-one cause of account takeovers. A strong password should be long, random, and hard to guess or brute-force.
What determines strength
The core is 'entropy' — the number of possible combinations. Length matters more than a complex character set: 12+ random characters are usually safe enough.
How to generate strong passwords
- At least 12–16 characters
- Mix upper/lowercase letters, digits, and symbols
- Avoid dictionary words, names, birthdays
- Use a different password per account
- Store them in a password manager
Make it concrete with a tool
FreeToolset's password generator creates high-strength passwords locally at random, and the strength checker estimates crack time — all without upload.
💡 Avoid 'Pa$$w0rd'-style 'complex' but common variations — they're already in crack dictionaries.
