ตัวสร้างรหัสผ่าน

This generator draws from a cryptographically secure source of randomness (the Web Crypto API) right in your browser. No password ever leaves your device or reaches a server.

How to use it

• Pick a length — longer is always stronger; 16+ characters is enough for most services.
• Turn on the character sets you need: uppercase, lowercase, digits, symbols.
• Exclude easily confused characters (0/O, 1/l/I) if you'll need to type the password by hand.

What makes a password strong

Strength comes from entropy — length and the size of the character set — not from how "complicated" a password looks to a person. A long password made only of lowercase letters is often stronger than a short one mixing every character type.

Where it's supported, turning on two-factor authentication does more for an account's security than relying on password length alone.

Things to keep in mind

Don't reuse the same password across services — a breach on one account shouldn't put the others at risk.

Store passwords in a password manager, not in a text file or notes app.
