Password Generator
Generate cryptographically secure random passwords. All passwords are generated on our server using secure random number generation.
Characters to exclude from the password (useful for avoiding ambiguous characters)
Cryptographically Secure
Uses crypto/rand for true randomness, not predictable pseudo-random generators.
High Entropy
Longer passwords with mixed character types provide exponentially more security.
Best Practices
Use unique passwords for each account and store them in a password manager.

Password Security Best Practices
In an era of frequent data breaches, strong passwords are your first line of defense against unauthorized access. A truly secure password must be random, unique for each account, and long enough to resist brute-force attacks. Human-chosen passwords tend to follow predictable patterns that attackers exploit, which is why randomly generated passwords are always the better choice.
Password entropy measures how unpredictable a password is. Each additional character exponentially increases the number of possible combinations. A 16-character password using all character types (uppercase, lowercase, numbers, and symbols) provides roughly 105 bits of entropy. For comparison, an 8-character password with the same character set only provides about 52 bits -- making it over a septillion times easier to crack.
Why Random Beats Memorable
No Patterns
Randomly generated passwords contain no dictionary words, keyboard patterns, or personal information that attackers can guess.
Maximum Entropy
Each character is independently selected from the full character set, ensuring the highest possible entropy per character.
Breach Resistant
Random passwords do not appear in leaked password databases. Attackers cannot use common password lists to crack them.
Password Manager Friendly
Generated passwords are designed to be stored in a password manager, so memorability is not a concern -- security is what matters.
