How this password generator works
This password generator works by randomly selecting characters from the sets you choose, including lowercase letters, uppercase letters, numbers and symbols. Each password is created instantly in your browser using a secure random number generator, and no generated password is ever saved or sent anywhere.
Choosing character sets
Choosing character sets to include lets you control the composition of your password. Selecting more sets increases the total pool of possible characters, which makes the password harder to guess. For maximum strength, enable all four character sets.
All chosen characters versus each chosen set
All chosen characters mode combines every selected character type into a single pool and draws each character randomly from that combined pool, which can occasionally favor one set over another by chance. Each chosen set mode rotates through every selected type in turn, guaranteeing a more even mix across categories before the result is shuffled.
Which mode should you choose
Which mode should you choose depends on whether a website requires a minimum number of each character type. Each chosen set mode is useful when a site mandates at least one symbol, one number and one uppercase letter, since it guarantees representation from every selected category.
Password length and security strength
Password length and security strength are closely linked because every extra character multiplies the number of possible combinations. A 12 character password using all four character sets has roughly 6 times 10 to the power 22 possible combinations, making brute force attacks impractical with current technology.
Recommended password lengths
Recommended password lengths vary by account sensitivity. Use at least 12 characters for general accounts, 16 characters for important services like email, and 20 or more characters for financial or administrative accounts.
Reference table for character set sizes

|---|---|
| Lowercase letters | 26 |
| Uppercase letters | 26 |
| Numbers | 10 |
| Common symbols | 8 |
| Extra symbols | 13 |
Frequently asked questions
A strong password is long, random and uses a mix of character types including lowercase letters, uppercase letters, numbers and symbols. Length matters more than complexity, since each additional character multiplies the number of possible combinations an attacker must try.
A password should be at least 12 to 16 characters long for everyday accounts, and 20 or more characters for sensitive accounts such as email or banking. Longer passwords are exponentially harder to crack through brute force methods.
Yes, an online password generator is safe to use as long as it generates passwords locally in your browser and does not store or transmit them. This tool creates passwords entirely on your device and never saves the generated characters.
All chosen characters combines every selected character type into one pool and picks randomly from that pool. Each chosen set rotates evenly through every selected character type so the password contains a balanced mix from each category.
Yes, including symbols in your password increases the total character pool size, which makes the password significantly harder to guess or crack. Combining symbols with letters and numbers is recommended whenever a website allows it.
No, you should never reuse the same password across multiple accounts. If one account is compromised, reused passwords allow attackers to access your other accounts too. Generate a unique random password for every account and store them in a password manager.
