Password Generator
Generate strong, secure passwords
What is a Password Generator?
A password generator creates random, high-entropy passwords that are practically impossible to guess or crack through brute force. Password strength is measured in bits of entropy-each bit doubles the number of possible combinations an attacker must try. A truly random 20-character password with mixed character types provides around 130 bits of entropy, which would take billions of years to crack with current technology.
How to Use
- Adjust the length slider — longer is always stronger (20+ characters recommended).
- Toggle character types: uppercase, lowercase, numbers, and symbols.
- Click the refresh button or adjust settings to generate a new password.
- Copy the password directly into your password manager for storage.
Frequently Asked Questions
Why does length matter more than complexity?
Each additional character multiplies the total combinations exponentially. A 20-character lowercase-only password (26 to the power of 20, about 94 bits of entropy) is stronger than an 8-character password using all character types (95 to the power of 8, about 52 bits). Length is the single most impactful factor in password strength.
Should I use a different password for every account?
Absolutely. When a service is breached, attackers immediately try those credentials on other sites (credential stuffing). A unique random password for each account ensures that one breach cannot cascade. Use a password manager to store them.
What does "exclude ambiguous characters" mean?
Some characters look similar in many fonts: 0 and O, I and l and 1, pipe | and l. Excluding these makes passwords easier to read and type manually when you can't paste them, without significantly reducing entropy.
